I don't believe that the original author is making the argument that "marketers sometimes do shady things with data." From its title and lede to the end, I read it as "some of these games are manipulative and use manipulative tactics and mechanics to suck money out of people, sometimes to their own demise. The government needs to regulate this industry to protect people from themselves and ban these mechanics." This is roughly as simple to regulate and ban as it is to ban any other type of mechanic. It is what leads to weird laws such as some of California's casinos having weird bingo-based slot machines, or pachinko machines in Japan needing you to trade a pseudocurrency for goods.
The point I'm trying to make is that it is impractical, costly, probably impossible and dangerous to attempt to limit the mechanics the OP is really pissed off about in a way that does not also impinge upon the freedom of the majority in order to protect those with poor impulse control.
I am capable of going to a casino and walking out of there without losing my shirt. I am equally as capable of going to have a few drinks at a bar without becoming an alcoholic, or to have sex with somebody and not turn into a raging sex addict. Should my ability to go to casinos, drink, or sleep with people be regulated too, just because some people's lives are ruined by these things?
You can project this argument into a thousand different things just because people like them. For example, I spend an absolute eternity on the Internet. The vast majority of my life is spent reading, writing code, or doing other coder-type things. Because of this, I have also had to eat the opportunity cost involved; I have missed out on some social gatherings, I have lost friends and also lost any and all experience I would get otherwise. It's safe to say, by some general decree, that I'm addicted to what I do. I'd argue I'm passionate. Should my work and passions be regulated because there is an opportunity cost to me doing so? Should I not be allowed to have the Internet at all because someone else has racked up inordinate amounts of debt at World of Warcraft?
I don't believe it is the fault of the mechanic that these people have poor impulse control, for some reason or another, and I also don't believe it's fair to limit the existence of these types of games because some people are incapable of walking away from them. If we should do anything regulatory down this path, it is building in proper harm reduction systems for these things versus taking a puritanical "ban it" approach to them.
