For me the most annoying one is the cookie consent banner. Very few sites have clearly defined buttons like “Allow all” “Deny all” etc. but majority of them have a (intentionally) convoluted UI so that a lot of users just accept all.
I frankly wish the web standards group had released an API for these so they could be handled at the browser level.
We've had multiple standards, mostly recently https://www.w3.org/TR/gpc/ . They always fail, because they're never mandatory, so surveillance capitalists just decline to implement them – or, worse, quietly sabotage them.
