YouTube Orders 'Invidious' Privacy Software to Shut Down in 7 Days * TorrentFreak

The developers of Invidious, a privacy-respecting alternative front-end for YouTube, have received a cease-and-desist notice from YouTube.

TL;DR: YouTube sends a Cease and Desist email to the Invidious team for API abuse (even though they don’t use the API.)

I also want to point out (since nobody else has) that YT has done shenanigans like this in the past. Invidious is not going down without a fight.

UPDATE

As of 2 weeks ago, Google has begun blocking multiple instances from accessing their services. This also includes my own instance and appears to be done alongside the C&D. (Note: I have not received one yet.) I’m currently playing whack & mole with Google and will be moving between several different servers. Some others are going through IPv6 addresses (which didn’t work for me.)
