Wikipedia is constantly running ads. They're just "charity" donation ads so you don't think of them as such, but turn on the TV and you'll notice that charities advertise themselves to get donations all the time. It doesn't make it not advertising.
As for HN, how long have you been using it? Are you aware it's ad supported? Some stories are ads, usually for hiring.
You are allowed to think differently, but personally I'm fine with the banners on Wikipedia (except IIRC and AFAIK they pretended they were short on money while in reality they were expanding).
I'm also fine with YC running job ads on YC.
I'm however not fine with 100 - 1000 [1] ad and tracking networks pretending they have reason to log my browsing habits on a typical site.
[1]: based on copying the list from "cookie banners" to Libre Office Calc and checking how many lines I got.
- programming blogs that doesn't have ads
- Wikipedia
- three or four online newspapers/websites that I pay for anyway.
- HN
- all the old stuff: web rings and enthusiast web sites
- I'd probably miss stackoverflow but I use that site less and less these days anyways.
Most of the rest can burn and we'd maybe be better off. At least search results would be cleaner :-)
