I won't speak for anyone else but in many ways I clearly love the game, though there are things I find frustrating. I've played it since the early '80s when I was a kid, off and on. Right now some version of D&D is all I play (a bit frustratedly as I'd like to play some other things). The issue is that one needs to get a group together and D&D is undoubtedly the easiest thing to get together with.
I don't much like the publisher's behavior. Loving the game isn't loving the publisher.
I totally recognize that the publisher needs to make money. Some repeated content is OK. In fact, 1E had quite a bit. The PHB, DMG, etc., all were essentially collections of Dragon articles with some added content. MM2 collected a lot of monsters that were in modules already. Content dumping is a problem, too, so I get the desire to avoid doing that. It creates a lot of fratricidal competition and market fragmentation among the publisher's own offerings. What I don't like about the current publication model is that they seem to have done a 180 turn away from publishing nearly anything. No Dragon or Dungeon, for instance. Pretty much the entire model is turning towards WotC generating little new content at all and just figuring out how to license what they've already written.
