I've had Premium since it was called Red (got it through Google Music) and never see ads. Would be upset if I was OP, but haven't experienced that issue myself.
I'm also a premium YT subscriber and if I see this or they kick me off for using PiHole, I'll cancel my account and just set up some automation with YT-DLP to Plex or Infuse for channels I like watching. If youtube decided that it's their turn to get shitty like the rest of the popular internet, I'll be beyond upset.
You can actually set up firewall settings to block any traffic coming from the ads, the only way they can stop that form of ad block is to block the person's IP address.
I'm mainly worried that some of the people I like watching on youtube will decide that youtube isn't worth it anymore and they'll stop making content entirely. Or even switch over to twitch, which I've never been able to get into.
I like the game grumps and Lex Fridman. The documentaries are cool, but I have to watch them in a different container or YouTube will start feeding me 30 minute ads or rants that sound reasonable but are super bigoted and flawed when you actually think about it
Reddit meant more to me than anything else I do online, and I committed to leaving it behind even before I found Lemmy... YouTube is barely worth it even without the ads. And I've got a whole fediverse of video content to investigate
