Are ads annoying - sure. But so are paywalls, so are websites that are entirely VC funded and desperately growth hacking until they can sell out to a bigger company.
The web is an expensive thing, very expensive. By not blocking ads I'm doing my bit to help fund it. I see ad blocking as a lot like piracy: understandable in some cases, but still basically freeloading on those of us who support the creation of the content.
