You know a company is mismanaging things when they're doing things that are against their own interests.
Can't you just make another account for videos?
It’s an extreme example, but if that account is true, google definitely have automated tooling to link distinct accounts.
I can’t actually imagine any reason why they wouldn’t. It feels like something they’d need at their scale.
Sure, in some ways, the fusion is very convenient.
But I've read a few too many credible stories about how a loyal Google customer does some innocuous action that happens to set off one of Google's triggers, and is instantly banned from the entire ecosystem.
Google's complete lack of customer support, and indeed hostility to the concept of ever being reachable by or accountable to a user just makes it worse.
Bottome line; Google is ok for casual use, but as a biz, I'll never touch them, and advise others to avoid like the plague.
