> if everyone did that, there would be almost no more free websites
Wrong.
Let's ignore for the moment that ad-funded websites are not free but only pretend to be free (the average user pays eventually, otherwise ads would not make sense for the advertiser), non-commercial websites have existed longer than ad-funded ones. If anything, making "free" profitable invites profiteers that produce mediocre content but know how to out-SEO genuine free websites.
> So much of the internet is paid for through ads.
And the best thing for the Internet is if that part came crashing down. But even for the ad-supported part of the web, almost all of the actual content is generated by unpaid users.
You have no idea how I LONG for a return to that. I DEEPLY wish every single person would install an ad blocker. If ad supported slop went under that would leave us with just paid and passion projects, and we would be far better off for it.
