There is apparently also a "Donation Edition" -

    Everyone who donates is eligible to download a special 
    version of FreeFileSync without any advertisements,
    including a few of bonus features.

It is built from a different source, so it's neither free or open source. Not that anything wrong with it, but it should probably not be distributed under the same name - https://freefilesync.org/faq.php#donation-edition

This project is kinda wonky from a free/open-source perspective. It's ostensibly licensed under GPL-3 (i.e., there's a source zip which has a License.txt that's GPL-3), but it otherwise acts like freeware with a single developer.

It has a history of bundling file-droppers/malware; there's a donation edition with a different feature set, with some extra features (including removal of arbitrary limitations on the regular versions); the installers are binary blobs, and there's no attempt (and passive hostility) towards integration with distros and package managers; source control isn't provided, and there's basically no attempt to create a dev community.

The binary installers may or may not include things that are not in the provided source code, like installer and ad systems. That's not really cool.

That's a hard pass from me. I will keep using Seafile and supporting FOSS by paying for hosting.

I've been through tons of different file sync/backup solutions but once I landed on seafile I haven't looked back. Truly awesome software, does one thing really well, upgrades are a breeze, I can run it in a container that bind mounts zfs volumes for storage and MySQL database so I can even snapshot those. Love it!

Have you tried synching? It is what I currently use and I would be grateful if you can share your insight on how they compare.

It seems like it serves the same kind of purpose as SyncThing (https://github.com/syncthing/syncthing).

SyncThing seems like a safer bet (better community, proper OSS, etc). :)

Last I checked, it looked like the difference was entirely in the installer, with the program just checking for a registration file at run time. Has that changed? Was my assessment wrong?

There apparently also was a Malware Edition: https://news.ycombinator.com/item?id=29662608

It's technically a recurring donation too if you want the current versions, for €20 you get 1 year of updates.
