If you feel a multi-million dollar need to influence public opinion, mostly in the US, because your current actions have made your approval ratings drop off a cliff, maybe this is more the time to reconsider the actions that led you here?
Other than that, this is probably par for the course now. Russia is surely doing a similar thing. And whichever military conflict the US might find itself in in the hopefully far flung future, they would do the same probably. First casualty of war and all that.
I fear this will be an uphill battle for YT. I have this gut feeling that Meta and OpenAI here are employing the flooding the zone strategy to hurt and maybe displace YT. The sheer flood of slop with the occasional enjoyable nugget of content flooding YT from the pAIrates will be harder to filter out, clog up servers, and users like you and I will get annoyed and gradually consume less content. YT loses market share and some new platform can move in for the kill, operated by Meta, OpenAI and/or other such reputable companies. It's not easy to monetize this crap, which is a loss leader at this point. It doesn't look to me like enough people will subscribe to these services to be financially viable. They have to find other ways. So pivot to video 2.0 - this time with so-called AI! Sigh.
