True. But most of the platforms used by people around the world to communicate (social media, instant messaging, etc) are owned by US companies. So our shitbag of an upcoming President could have a global impact in this regard.
That being said, I don’t find myself particularly worried about this specific thing. Hopefully I don’t eat my words.
Jellyfin/Plex like many have mentioned.
I personally like Syncthing for petty much everything else. For general file syncing of course. But also with Joplin pointed to a synced directory for notes. With keepass as a password vault. With synced config directories for some apps across devices like newsboat for RSS, and neomutt for email. I also used to use it with rtorrent via a watch directory, though I currently am using a seedbox for that purpose.
VPN (openvpn/wireguard) is a good idea if you want to access your services outside your local network, without exposing them all globally.
