>small, irrelevant websites that resemble what existed in the 1990s.

I take issue with this statement. The websites back then were small but they were not irrelevant. If anything they featured more relevant and original content than the majority of sites today. Combined with the tech of today like free CDNs I don't think we'd be much worse off.

I would enjoy it. I doubt you would enjoy one day getting some random malware through your ads that you leave unblocked.
