Ahh google, the `great' advertising company!
Oh nice one, they've decided to block all of Blender's videos on youtube because they don't want to turn on advertising.
Essentially blackmailing them into becoming part of their slurping adversiting empire where they get to make most of the money from peoples labour whilst paying a pittance. Despite not being a real user of it, as one of the original supporters who helped fund the freeing of Blender way back when with a few hundred dollars I'm pretty apalled they would be treated this way (although not surprised).
Fortunately the technology is coming together so that alternatives exist to a monolithic/expensive server such as PeerTube which uses WebTorrent, or InterPlanetary File System (IPFS), and others. blender.org is experimenting with a peertube instance at video.blender.org already.
Of course that only works so long as bittorrent isn't blocked, or WebRTC isn't blocked, or backbone operators start to throttle protocols competing with those that are part of their corporate conglomerate or have not been paid for. Or regulatory capture though some pro-establishment law effectively bans it (like the EU Copyright `Article 13' crap happening now).
Even if some backlash makes them change their mind it's just another example of the problem of corporate centralisation/ownership of culture.
