The internet is in a real sorry state nowadays, there's no denying that. Analytics and marketing have thoroughly trumped functionality and accessibility.
Best way I've found to work around all this crap (other than just browse the internet less, depressingly) is through Pi-Hole, uBlock Origin and Privacy Badger installed in every browser. Mobile is trickier but Firefox/Brave mobile get the job done as they do allow plugins so I can run uBlock there too and enable the cookie banner filter.
