So much. So, so, SO much.

Websites in general. More bloat, more CPU usage, worse design, less content. This is even worse for shopping sites, USAians probably only know Amazon, but people from other countries definitely know a big local name that used to have a much better site years ago compared to today.

Smart TVs are the worst. You're better off buying a shitty china android tv box than a smart tv, both will suck up and sell all your data, but at least the latter can be kept off when you don't need the "smart" part.

Smartphones. Not only the whole "LETS COPY APPLE" on hardware and software design, but also on how fast it's doing a lot of the stupidity that followed PCs: phones keep getting more powerful, programs keep getting slower and more resource intensive because ~~fuck you~~ "new features"

Ad tech. Yes, I'd glady go back to shitty popups over clickjacking, infinite redirects that don't show up on the "back" button, annoying anti-adblocks, 70% of pages being advertising and fingerprinting bloat, javascript/css having control to FUCKING HIDE AND DISABLE MY SCROLL BAR

Tinder. It was good 10 years ago, enshittification accelerated aroudn 2017. Free accounts have had a hard time getting any matches as far back as 2019, as I recall from experience. Nothing like having received "41" likes, going through 300 profiles with "nope" and not losing a single match.
