It's certainly true that many free to play games fall into this category, but definitely not all of them... I don't do a lot of mobile gaming, but I do know there are decent games out there that won't make you hate your life with inane calls to action. Robotek is an example of a great free-to-play game that does use in-app purchases, but doesn't require them (games that claim not to but basically do if you want to actually get anywhere are horrible). Anecdotal evidence is crap, I know, and this is only one example (I've played others but can't recall them right now)... but the top earners are obviously always going to be the kind of money-pit BS you're talking about. That's a shame, but putting all free to play games -- with or without IAP/advertising/etc. -- into that category just isn't realistic.
