I have a Matrix acc and joined several rooms of FOSS, but sadly it looks like most of them are still less active than their Telegram/Discord counterpart.

I stick with KDE (Kubuntu) after using GNOME, KDE Plasma, and Cinnamon. I think GNOME lack some settings available in KDE, KDE is the most customizable with a good default, and back then Cinnamon doesn’t have Wayland that some of my apps, especially Waydroid, need. The only thing I hate about KDE is the wallet that keeps popping up by default. GNOME keyring is better IMO. I’m a heavy terminal user tho, for automation with bash script and easier copy-paste from Arch Wiki etc., so mb I not quite representative on DE.

I’m a Taiwanese and interacted with a bunch of Linux users from Mainland China on Mastodon. From what I saw, I don’t think it’s as easy to use Linux in China, mainly due to the Great Firewall. They often need to tweak the mirrors and even tunnel through their VPS overseas.
