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.
No business should never depend on a single third-party service
Unfortunately, it's not as simple as asking nicely. Self-hosting costs money especially with huge files like videos. If you have a cheap hosting plan with something like 500 gigabytes of bandwidth and you have a moderately popular video, the web visitors will get a "bandwidth exceeded" error message. Self-hosting videos is a huge costly leap over serving static HTML files.
Hosting videos on others' platforms like YouTube/Vimeo/etc gets past the bandwidth constraint.
[Edit] "government censorship seems to be becoming the norm" is perhaps too extreme. Still, the link between the article's evidence of increased censorship and the Trump administration's stance on climate change (and other issues) is concerning.
