Subscriber here. I use YouTube pretty much all day long. I usually have it playing something for background noise while I'm working. I've got a family plan with 4 other people on it, who all also get the benefits of ad-free viewing.
I also use YouTube on several devices of my own. TV, PS5, phone, tablet, three laptops... Trying to manage adblockers on all of those is such a pain in the ass. I'll never go back to troubleshooting Pi-holes and adblockers and adblocker-blocker-blockers. It's an objectively worse experience having to manage all sorts of goofy tools that keep getting circumvented by Google every week.
Also, the content creators I watch get paid for my views. I spend hours watching these people's content, so making sure they're getting paid means something to me.
