I just got the same warning on FF with uBlock. Both Freetube and NewPipe seem to be fine though. I guess Freetube it is until uBlock is patched.
Edit: Also, glad I’m not the only human watching Grossi’s videos today lol.
I just checked a bunch of random videos, ff with uBlock, none of them displayed this message.
I believe they tend to roll these out in batches. It creates less uproar than hitting everyone at once.
Somebody else mentioned possible region tests, too. I can definitely see them doing these things.
I wasn’t trying to be like “well it didn’t happen to me so it’s not happening” at all. I fully expect to see it eventually. I hope not though.
