Has the possibility occur to you that people say it not to be funny, but as a form of tough love in hopes he gets his shit together? I get why you would only want nice things said about him, but it's kind of hard for other people to say nothing and have a clean conscience, knowing he's doing this to himself. I'm frustrated with him, but I also remember what he was like beforehand. Forget his OF, even his acting ability has seem to decline since he started getting heavy into drugs.
Again, I get that you like him a lot and only want to see nice things said about him, just know the criticism he's getting isn't baseless and not just for the sake of hating.
