Earlier quoted context omitted.
Time to start regulating these games in the same way we regulate gambling. They shouldn't be sold to children. They're not Kinda eggs nor LOL Surprise and should never be brushed off as surprise mechanics. They're glorified slot machines, through and through.
Apple/Google revenue will see a big decline if those games are regulated. Most if not all the top grossing games on mobile follow the same spending pattern, and a big chunk of app stores' revenue come from those games.
Of course that was caused because the app-"economy" was broken from day one on: You couldn't and still can't call out fair prices on mobile software. People weren't and aren't willing to pay those. So you have to make the software "free" and sell your user's data, or charge one or two bucks and use some other immoral scheme to get your actual costs covered.
On a broken market there are only broken products… Simple as that.
