That's how you know it's bullshit, because every major ad blocker allows you to disable per site. There's no need to uninstall. The claim that they're being uninstalled was written by uneducated propagandists.
yeah like who has a few days of youtube ad blocking not work then goes "that's it im uninstalling this ad blocker and going back to ALL THE ADS EVERYWHERE
You vastly overestimate the average user. Probably installed an ad locker cause heard from a friend or coworker. Then stops letting them watch YouTube so they uninstall. Go to a non techie and browse the web it's insane.
I know someone who is non-technical who asked how to remove the ad blocker they had when YouTube displayed the message, as they didn't know you could turn it off per site, so anecdotally that is something that does happen.
Considering that, after Netflix enabled anti account sharing, they got an increase in subscriptions, I've lost faith in humanity, and believe YouTube will succeed in the same way
But that's because most people watch Netflix through smart TVs and those TVs are closed systems that don't have apps, or very limited ones. Trying to get people who barely understand how to operate their remote to stream from their computer or other device, isn't going to happen.
