My oldest bank account has a website that used to be very accessible, fast, and widely used, with several 3rd party parsing libraries on GitHub that would, e.g. scrape the whole lot and put it in a CSV for you. They then "modernised" it. The whole thing is a JavaScript nightmare, with only one static page, over-ridden OS shortcuts and a very confused browser autocomplete -- oh, and a ton of tracking tags. A grease monkey script and uBlock bring it back to useable, but I'm still silently shopping for new banks entirely because of how utterly ridiculous and user hostile it is.
