Personally I won't judge people for playing mobile games, there are some good ones out there, but most of the ones I've seen seem very streamlined towards player monetisation, or are slot-machines by a different name - it's the same reason I often won't play "Free to Play" games on PC either.
I'm curious as to what genre of games you play, because some absolutely would benefit from touchscreens (i.e. visual novels, point-and-click games), but I can imagine most others would fare better with traditional controls (even at the expense of portability)
Edit: Having actually seen these games you refer to, I can see they're very much part of that former category, and are very reminiscent of flash minigames I played as a kid. I would personally consider minigames as a different thing to games proper, as they're much more shallow experiences, so maybe that is what you're running into with people saying they're "not real games"
