That guy is just talking profits and then tries to justify that talk, it shows through and through. And there's an entire widespread branch of the video game business that really begs to differ, especially the indie one, but of course King isn't the kind of company who'd see that. The fact that they assume free to play like it's the only feasible line of revenue, and that everyone WILL ADOPT IT OR ELSE, pretty much shows that they're just spreadsheet-marking their profit assumptions based on "what is trending" rather than "what would be interesting to do".
Why does video games have to be the end getting caught in that kind of a pit? They're taking an entertainment media and treating it like anything but, taking all the attention from the "entertainment" part and pushing it all on the "how do we make quick money" part. Even the "big and evil" music industry knows contemporary pop idols are just one out of thousands of genres people listen to. Pacific Rim and the expansive Avengers series probably weren't funded because marketing said giant mechs, kaijus and superheroes were mainstream hits. Pixar probably doesn't consult profit spreadsheets when plotting their movie ideas. George RR Martin didn't write A Song of Ice and Fire because medieval murder plots were "a thing", nor did people try to adapt it to a TV series because medieval murder plots were "a thing".
So why the hell are companies like King, and so many other proclaimed tops of the game industry, so locked up in that abhorrent frame of mind that "these things appear to be a trend right now, so everyone should do those things"?
It's just silly, and self-destructive. But at least it's giving indie developers plenty of elbow room while some of these big-cheese* blokes are busy being idiots
(*Wanted to say big-budget, but King's entire repertoire could be done without much of a budget at all. The only thing those guys are big on are themselves.)
