Hmm this is a tough one. Firstly I should make it clear that my wife works in the games industry. She works on PC, Console and Mobile titles. She has mentioned several times how there is a lot of pressure put on developers and publishers to "catch the whales". They employ psychologists and gambling specialists to make games, mostly mobile but it is also creeping into PC and Console, super addictive.

Personally I am of the opinion that people should be able to do what they want* but my wife is genuinely concerned about just how they go after certain types of people. They do want to get the gambling types. They are the people who spend money. Lots of money. I have seen numbers where people who obviously have more money than we can imagine spending $50-100k on IAPs. Some games even have "limited" IAPs that were designed for just one player as they spend so damn much.

However I can't help but feel there is something else behind this post than what the author seems to spin it as. What I am not too sure but it seems quite the ramble and he doesn't actually have any solid sources or data to back up his claim. Of course neither do I outside of what my wife tells me :)

* Okay so there has to be some limits.

Edit: I would like to make the point clear that while I think people should be able to do whatever they want, I do find this kind of predatory game design unethical. As does my wife. Thankfully nothing she has had to do so far has been totally deplorable.
