A website chooses to serve ads. You don't like it? Don't ever go (back?) to that website again, I'm sure there's some blacklist extensions out there.
Just because you don't like ads or tracking (neither illegal) you don't have the right to cost that website money (bandwidth, etc.) without anything in exchange.
Actually it's good that some sites are ad-funded. E.g. news sites. Ideally that kind of site would offer a paid, ad-free, tracking-free option for people with cushy jobs like the HN crowd. But Mr. and Ms. Can't Make Ends Meet can still access the news in exchange of seeing some (or a lot of) ads here and there.
At the very least, if there's an ad-funded website you like and visit frequently then disable ad blocking for them.
