I don’t think we should underestimate the savvy programmers out there, who are just as fed up with ads as the rest of us.
And at this point, most of the cousins who don’t know how to update their adblocker are already there. It’s a matter of time. YT won’t keep pouring money into this. Just long enough to the “balance the books.” When the ‘number of viewed ads’ start slowing down again and they’ve hit their max viewership, they’ll call off the hounds.
