Ramin, while I appreciate your passion for the topic of Free to Play games, I have to say this article is overly simplified and borderline insulting. First, you seem to be conflating childhood development and personal responsibility in one article. It is easier to address these problems if the two are separated.
You seem to be implying that F2P developers are preying on children. While there have been examples of children buying copious amounts of Smurfberries, these are the exceptions, not the rule. To imply that the companies making these games are specifically seeking out children in order to exploit them for their copious disposable incomes is ridiculous. If these companies were specifically targeting children for exploitation, they would be in violation of COPPA (Children's Online Privacy Protection Act). I'm sure that the first time a game company was found in violation of COPPA, it would be all over Gamasutra, but this hasn't happened yet because F2P developers aren't doing anything that violates rules specifically set up to protect children in an online environment.
Looking at the OFT principles as proposed by the UK government, most of the F2P games (I've played) are either in compliance already, or need a few text changes to get there. You frequently bring up Candy Crush Saga as a game that is going to be heavily impacted by these new OFT rules. Comparing them with what is in the game now, there are exactly two areas in which they are not in compliance. The first can be fixed by changing the text on the game over pop up by adding the line "or wait to continue for free". The other is "principle 8" which requires changes from the platform holder (Apple, Facebook, Google Play). Even the OFT committee states that Principle 8 will probably not be enforceable against the game developer. If these principles, which are specifically designed to protect children, only require minor changes by a developer, I find it extremely hard to believe there is some nefarious child-preying going on in the F2P development world.
I've seen this number thrown around quite a bit about brain development not being complete until 25. This number is taken way out of context when it comes to F2P games. Child development theory states that children reach the ability to use formal (logical) reasoning somewhere around the age of 12-14. Even if you add 5 years for developmental differences, this means most people are capable of rational thought by the age of 17-19. It is not a coincidence that the age of majority in most countries is around this same age. This type of reasoning should be sufficient to be able to look at a pop up that says "buy more gold?" and say no. But what does that 25 years to get the brain fully developed actually mean? It's talking about post-formal thought. This is the type of thought that allows adults to sympathize with others who hold abstract beliefs that are different than theirs. In fact, some psychologists believe that a good number of people are incapable of developing extremely abstract thought. However, this is not viewed as a disorder or disability because that level of complex abstract thinking is not required to live a fully functioning, complete adult life. Hardly something needed when declining a purchase in Candy Crush Saga. If you look at where F2P game choices fall on the model of hierarchical complexity, this example scores on the low end of both the horizontal and vertical axes. In fact, it's not even abstract. These pop ups are literally asking a direct question (buy stuff?) with a dichotomous result (yes / no). So while it may be true that the brain does not fully develop in some people up to the age of 25, that number is completely irrelevant to the F2P discussion.
So let's look at adults and F2P games. Is it unethical for F2P developers to ask players for money? The argument you are trying to make is yes, because there could be people out there with physical disabilities that could be vulnerable to lowered impulse control. While this might be true, it's also true in every area of life. Are we to start regulating frozen food makers because they have pretty cool packaging and delicious chicken nuggets? Should we stop distributing coupons because people could see the savings as irresistible and blow all of their money on Healthy Choice pudding? No, this is absurd. There is a level of personal responsibility that you have to assume adults have. Otherwise, our personal freedoms would be so restricted, we couldn't do anything. There is a theory in psychology that states this hand-wringing over the safety and responsibility of others is actually damaging to people with diagnosed psychological and developmental disabilities. People need to feel like they have control over their lives. Regulating what they can or cannot spend their money on is not the way to do that.
I get that free to play is an easy target. Five years ago, games like Farmville and Mafia Wars challenged what "Games" meant. A lot of game developers were insulted that glorified spreadsheets and cartoon dollhouses were being called games. There's a lot of truthiness in what you are saying. It feels good, and it makes "real games" seem more legit. However, I haven't seen any suggestions on how to improve the situation from you. You call out a lack of compassion, and yet offer no suggestions. You say "think of the children!" but have not produced any examples of how you could do it better. Even worse, while disparaging developers who make games for kids, you have not given any recent examples of exactly how they are doing this. I've tried finding your papers, and while I have found copious blogs, I haven't found any academic works with your suggestions. Recently, you have said that you are working on World of Tanks. I can only assume this game is the result of your proprietary work on developing a new F2P system. Let's examine World of Tanks: It has premium currency. It has paywalls to exclusive content. It has premium items that give advantages to players who spend money. It has feedback loops that encourage constant play. In short, it's exactly like most good F2P games out on the market.
You are building a career on platitudes and disparaging other developers, while producing nothing that can be peer-reviewed. To say that a mother who clearly cares about raising her children and a PhD candidate are lacking in compassion because they disagree with you is rude, unprofessional, and damaging to your own reputation.
