The better solution, if you don't agree with their new comment policy, would be to migrate to another video site like Vimeo.
That's why I mentioned flattr and patreon.
Streaming though... It obviously depends on the userbase, but I have downloaded feature length videos faster through bittorrent than youtube took buffering the first minute.
Another idea - maybe a middle ground would be pre-leeching episodes. I will want to watch them eventually, so might as well download ahead of time. Best of both worlds. Actually... that's exactly the kind of thing that would kill a centralized service like youtube, but would make a torrent-based service fly.
There are a number of reasons why that might have been in that particular case, but still, an interesting data point.
Giving up accessibility and mobile seems like the touch of death.
