I hope she keeps it on her YT channel. I don't understand why she just don't do what Hollywood Records did to their channel, just get VEVO to put a stamp on the video and it remains on her channel.
I'm happy its on vevo. The vast majority of video views comes from suggested videos. Vevo videos suggest other vevo videos. It's extremely difficult to be suggested to a video from Beyonce's own channel. Now that it's on vevo, people watching very popular videos right now, like AATB, SIO etc may also be suggested to watch this, wouldn't have happened was the video on her channel. So without being on Vevo the views would have drastically decreased as soon as it was removed from the front page. This will help it A LOT in the long run. It's not the ideal situation, but its Beyonce afterall...
