Your question is a bait since any sincere answer to that always gets downvoted. However, I've stopped caring so here goes:

I don't mind ads and have found many things I've bought through ads.

I don't want the page I'm visiting tampered with.

I want to experience the site exactly like it was designed, ads included.

I like to keep up with ad trends.

I'm afraid stuff will break and that I get a suboptimal experience without me even realizing it.

I want to support creators and certain sites.

I pay for YouTube Premium so not an issue there.

Do you work in advertising by any chance?

I would guess website design/front-end development. If that's something you do on your site then you'd definitely want to see what it looks like on others.

Yeah, you nailed it. I'm a front-end developer.

> I want to support creators and certain sites.

Well at least we can all agree on this one thing. How we get there without dealing with sites that load slowly, look like hell, and track me wherever I go is the big question.

I think ad-blockers are bad for the web. Their proliferation will create an arms race that will end in more DRM.

That's my reason.

I primarily watch YouTube on my TV via a Roku. It's probably possible to jailbreak it and install an ad free YT app, but that's beyond what I'm willing to do.

Some people feel that exposure to the ads is worth it to help the people who make videos.

It seems to me the ads do a dollar's worth of damage to the viewer while only giving a penny of benefit to the author.
