How is it freemium? You either pay them to "host" your files or you don't. There is no other cost involved. IIRC, Joplin Cloud is a similar set up if you're not equipped to selfhost or just don't want to. It's not FOSS, sure. But it's a hierarchy of flat markdown files that can be read by any text editor on any OS. Making extracting your data very simple. Joplin stores your notes in a database file that requires an export or conversion function to get it back out, should they go out of business, etc. The database and the absolutely horrible Android app is what had me give up on Joplin entirely. If it's working for you thats great. I'm certainly not trying to convince anyone. My use case requires easy, universal access to my notes. And .md files in folders is the lowest friction way I can think of. I'm currently paying for Sync, but once my year is up I'm going to try Syncthing again or the CouchDB sync plugin to save money. $8/mo is too much.
