The heart of the issue for me is all in how it's done. I don't even really care if the presentation is a bit cluttered or whatnot, so long as things aren't annoying me, I'm fine.
Annoying is having to do things like reach for the volume control, having to click somewhere because of tricky mouse-overs, popovers, fake dialogs, videos appearing in a screen filling overlay... things that in general obscure the content I have visited to see.
And to be clear, I'm not even talking about advertisements in a good few of those examples. News websites that start playing a recap of the evening broadcast just because I clicked to read a local article? There isn't a clickable advertisement in sight. Sometimes the content I clicked to view isn't even in sight. It's hidden behind this big streaming video that I didn't ask to see, and often has nothing to do with what I want to see. It's not even an ad.
And worse, they are having to pay for bandwidth to stream video that I do not want to see. Total waste of money and time.
What's interesting is that with quite a few small town news/newspaper websites, they'll have the article content in a narrow column, with many banner and column ads surround it, all from mostly local businesses. And this doesn't bother me a bit, nor do I have any inclination to block them. The content is there, and the prominent ads, even if a bit densely packed (even cluttered), respect my time and visit by NEVER forcing me interact with them unless I want to.
Passing billboards along side the highway, versus having to stop and move the signs out of the middle of the road so I can continue to drive.
