I don't mean to seem blunt or rude. I don't actually have kids, so even if I were inclined to judge, I've no basis. But just looking at what YouTube has been doing over the last couple of years, even as a premium subscriber and so never seeing ads - I mean, it's terrible, it's as if it is actively trying to drag me down a conspiracy theory rabbit hole, in the sense that I might watch a half dozen videos today about simulated jet-plane gunfights in DCS, and tomorrow I'm seeing recommendations for what I only recognize as "Intro to 5G Covid Conspiracy (CONT 101, 3 credits)" because I have studied the subject. I report these videos and they stop coming, until the next time.
It isn't as though there is a game here on the other side of which for there to be an adversarial mind, but there are times when it feels enough that way - when I'm half asleep, perhaps, and most especially - that I just don't even open the app or website entirely, but listen to an old podcast episode instead because those at least I can trust. (I pay subscriptions or buy copies; anything 'ad-supported' is a hard stop. I prefer people just say outright 'this is what I have and what I think it's worth, let's see if we can make an honest deal' because I am an American.)
I am seriously considering hosting a local Invidious instance, or similar, and terminating my now about ten-year YouTube Premium subscription. Ads are a technical problem that I was happy to pay a few bucks a month rather than however many hours to solve. I did enough years of sysadmin work for a living that I no longer enjoy it even slightly, so that's no small trade for me to consider. But now I'm really looking hard at what that money's going to, and by the sound of things lately, I'm among the least enthusiastic of such critics.
