Having to pay to visit all of the sites out there which are currently using ads would pretty much ruin the internet for most people. Having a big banner at the top asking for donations seems to work rather well, though. See gnu.org and wikipedia.org for examples (though Wikipedia's donation campaign this year is a bit excessive IMO).

FYI, you can hide the Wikipedia donation campaign banners by putting this in a userscript that @matches http://*.wikipedia.org/*:

    setTimeout(function() {
        fundraisingBanner.hide();
    }, 1000);

This ublock custom rule worked for me:

Or just sign into your wikipedia account.

I consider them ads and use adblock to block those as well.
