I never considered my loaded with addons UI ugly in WoW, but then I just customized it so that it presented the most essential information in the most efficient and esthetic form, having a complete clutter on the screen doesn't really help. It's less like doping and more like - if you want to be a good ski jumper, you need good skis, suit and have both of them really fitted to you.
Exaggerations aside, I'm not exactly sure what you guys want or expect. Wishing that the game didn't have addons because that's just what you want is think fair is a perfectly viable opinion, but so is one that any AAA MMO that comes out at this day is lackluster *cough*swtor*cough*.
TL;DR: the game has addons, some people will consider it a bad thing, others will consider it a good thing, neither opinion matters at this point.
