for example: people who don't have adblockers (like everyone in my family except me)
I won't visit websites with [a lot of] ads if my adblocker stops working. I'll simply stop using these websites. Just like before Netflix, I quit watching cable TV.
Thinking about it, I might as well go to Tor. Surely someone will copy/paste the plaintext content to some hidden service over there, just so the rest of us don't have to bother with ads. I might even be one of the contributors. If there is demand, there will be supply. And nobody is going to bother to "catch these copyright infringers" because nobody gets hurt, in contrast to someone selling illegal firearms or dangerous drugs.
People who don't have adblockers are willing to put up with a heck of a lot. Agreed.
But if someone is not technically sophisticated enough to use an adblocker, they're also probably not technically sophisticated enough to find the actual content on a page and just give up.
I see this fairly frequently; someone with limited computer literacy goes to a website from Google, doesn't see anything relevant immediately (because of bad UI or really bad ads), and goes back to Google. Often the site even had relevant content when I look later, they just couldn't see it because they aren't as good at parsing website content.
There are so many websites with equivalent information, if you click on one and it's just garbage at first glance I think hitting "back" is more likely than "read and click on every ad and give them your SSN before downloading their virus scanning software".
Maybe not most, for now. But there certainly exist people who do this. I do, for one.
