Because Vimeo sucks for the end user. Unless you're in a major metropolitan area, it's much slower than YouTube. Last time I checked it didn't remember the position in the video. With YouTube, I can start watching a video on my desktop and switch to my phone at some point - it would simply continue playing at the same point in the video and I don't have to wait (seek and time-before-playback-starts is awful with Vimeo). YouTube is technically superior product and it's much easier to use. If Vimeo wants to attract users, they first need to get on par with YT.
