I see you don't understand how the network works
The point is that I am not taking or using anyone's bandwidth but my own, that I expect websites to do the same, and that advertisers are uninvited interlopers in a private relationship. That's what peering is all about. FIgure out how to phrase your objections within that framework and maybe I'll believe some of your arguments.
What world do you live in? It's extremely obvious that YOU don't know how networking (or the real world) works. Networking is a two-way street.
At nearly ANY provider (above a dime-a-dozen personal blog host), a customer absolutely pays for bandwidth usage. Sometimes they give you a little for "free" - but it's still metered, and you're still paying for some sort of account. And of course, any usage beyond that has a cost. And on some hosts, if you have separate web and db servers (which is needed for heavy data/traffic), they meter that bandwidth, too (terrible host? Yes. But the point is that it happens).
I ran a website for 6 years that ended up with a peak of 5 million users. I co-lo'd my (eleven) servers: that's physical rack space (i.e. 'rent'), that's power, and that's bandwidth (not internal, but external. To the tune of hundreds of GB/day, even with 'optimized' assets and HTML). You can try to pick apart the explanation to spin some self-serving argument, but the inarguable bottom line is that these amounted to real costs - upwards of $1000/month at general cost, and that's not even including buying the physical machines. You're telling me I should have to pay out of my own pocket, out of the kindness of my heart, just because I built something that other used and enjoyed? I was unemployed for the first year I had built the site. It would have never gone anywhere at all without advertising.
I think you're oversimplifying your stance based on some assumption that the only non-commercial websites in the world are some kid talking about his cats or making political rants. There are tons of interactive, entertaining, and/or heavily data-driven websites that cater to, and are useful for, some subset of people - ones not selling anything, and not backed by corporate funding. Advertising is literally THE ONLY avenue for some - possibly 'many'; maybe even 'most' - of them. They do deserve to exist. That's what the internet is about.
If you want to go back to the 'good ol days' where every non-corporate website was a home directory on a university server, that's fine - Lynx is still around, and you won't have to deal with any advertising at all.
