It's not just adverts, though - the amount of pointless javascript on web pages these days is almost embarassing. The concept of optimizing web pages for quick loading and judder-free browsing seems to be completely lost on today's web designers.

Also completely agree. I find myself wanting the internet back from before all injecting all this JS became popular. I know that's going to make many JS guys pissy, but it's true.
I'd rather see people just rely on simplicity and HTML. The web should be about hyperlinked document sharing and simple data/storage retrieval frontends like github and email. That was the original use-case and shoehorning in more today is clearly just pissing people off.
Going too far beyond this with flashy designs kill usability, speed and productivity. I'm frequently having to cut down Google's attempts at messing up my Gmail with constant new JS features. I'd probably prefer just HTML Gmail too (https://mail.google.com/mail/?ui=html&zy=h) if they'd just do a little touch up work on it such as the ability add contacts. It's not missing much but is so performant and just what I need.
My general rule is if you can achieve what you need with just HTML, then stop there. That would probably be fine for 90% of the sites out there like my email and HN.
Corporation will push you content from their sever, including agressive advertisements.
It's (sadly) up to the user to filter them on his browser, on the front-end.
I manually disable my ad blockers on websites I choose as appropriate. The minute one of those website use an agressive ad that covers the content or a popup, it goes back on the blacklist.
