Whoa.
While I personally don't agree with all of Li's affermations regarding his animated short (nor do I think it's very good) and find myself more in accordance with Vimeo's stance, I do have a problem with their hypocrisy. If they find Li's film in violation with their policies, then the other cited examples in this article should also be excised; conversely, if they are allowed to stay, Li's film also shouldn't be banned.
Thoughts?
Oh…you wanna see it? Ok…
Never forget Rule 34.
While you touched on the Vimeo ban, no one has yet mentioned the "goose/gander" problem here with Vimeo. Maybe I should have linked to the other videos in question to see what Vimeo us allowing? Or, judging by the reactions here to only Li's video, maybe not...!
