If you don't like the ads, don't visit the site. Sites survive thanks to ads, and maybe donations, but that's rare, so if everyone thinks that way, websites will shut down and you'll loose all that content you like so much.
I admit I block intrusive ads in some sites, but I have no problem with ads in general. If I like the site, I disable the blocker, or I enabled the "acceptable ads" option in my blocker if it's available.
