I had interpreted the news as affecting all users of the other tools. Now found https://github.com/TeamNewPipe/NewPipe/issues/11139 with very few comments so I don't get the impression it's affecting many NewPipe users at present.
Newpipe is amazing, just keeps on going through a lot of Google's attempts to block it.
