I use adblock myself, and don't feel bad for using it (it's a security and privacy tool). But i don't blame websites that kick me out for it; hosting costs money.
Server owners should have all the right to set the terms of their server access. Better tools to control LLMs and scrapers are all good in my book.
I really wish ad platforms were better at managing malware, trackers and fraud through. It is rather difficult to fully argue for website owner authority with how bad ads actually are for the user.
