YouTube Blocks Blender Videos Worldwide

The fact that YouTube doesn't have an answer to Blender's ticket tells you all you need to know: This is /another/ Google snafu.
The answer is to distribute one's digital work widely across multiple means including those that don't need JS. Don't push people to run needless JS via PeerTube (Blender's PeerTube page is useless with JS turned off which is actually a step down from what YouTube allowed for some videos).
Instead host copies of the work in many other places such as places that don't require JS like archive.org (no JS needed, easy downloading and embedding anywhere). And encourage people to distribute copies in ad-hoc informal networks without tracking or JS.
