Right. If I request they snail mail me a copy of some document, they are free to reject the request. However, if they send me the document, I am free to tear off pieces or color on it with crayons.
Excellent point. I'd say there are edge cases to viewing a website too, but the claiming the general case falls under some sort of copyright-adjacent protection is bunk.
A bit more nuanced: not loading in the ad on a news site is akin to ripping out and throwing away the subscription card in the magazine. The contents of each might be subject to copyright, but that doesn't invalidate my right to separate them once delivered to me.
