Interestingly, I use Instagram with Mullvad for over a year now, both app and web. Reddit seems to be working fine too. Maybe that's because I opened accounts without a VPN.
I missed all the fun because there was no ads in my country, and the Amazon app was just a weird western thing removed right away. Unity was pretty good though.
The standard might be complicated if you want the specifics, but for everyday use it's incredibly simple, and I love it. The number of times I needed this information is 1, even though most of my devices, including an external monitor, are USB-C.
I'd be down if Discord offered optional/default compression for images/videos. Yeah maybe my photos are 10 MB each, but with a slight quality loss they can get under 1 MB. Telegram does it well.
When I used Mint, it felt like packages are outdated just like on Debian (based on Ubuntu LTS + needs time to rebase onto a new one).
