The solution for YouTube is right in your comment: it used to be the case that only tech savvy people would install AdBlock.
With more ads though, the incentive to install an ad blocker is suddenly there for more, even not so tech savvy people.
YouTube‘s reaction is already visible as they are now trying to block ad blockers: Try to make it more difficult to get an ad blocker at all, so not as tech savvy people won’t get one and continue to watch ads as they used to.
