Censorship aside, content creators should never depend on a single third-party service for hosting their videos, especially if they intend to make a living from that content. Google has already proven willing to remove arbitrary content, delete channels, etc. from Youtube with no apparent rationale or recourse given.

I suspect a lot of their recent "glitches" are an attempt to poison the well for public content and to drive potentially copyright infringing channels[0] away in order to eventually turn the service into an entirely subscription based, big media friendly platform. But who knows? The point is, it doesn't matter. Unless you're Sony, you might well wake up tomorrow to find your entire channel erased, and you'll never know why.

If your content is important to you, consider hosting it elsehwere, or else offering it as a torrent. It may require a bit more of a technical investment, be less convenient, and even reduce revenue, but in the long run, the more channels for distribution you have, the more you can afford to lose.

[0] infringing from the point of view of media conglomerates, who refuse to respect the legitimacy of fair use.
