I remember back some years ago, a more clued-in friend watching a movie with some generated backgrounds with me and groaning "Oh, god, not those Bryce fractals again!" Of course Bryce has its own albatross to carry around; its not-entirely-earned reputation for month-long renders. If I had to think about it, I'd say Bryce stays clear of the arguments because it isn't seen as in competition for the same eyeballs. Bryce art tends towards large magical landscapes, and for those it fights with Vue and Mojo -- not with Maya or Max. It is, perhaps, a little more self-policing. I think what annoys outsiders to Poser is that it behaves more like kudzu; turn your back and Poser crops up again -- and every time you cut it back it seems there's more and more of it.
