While I agree Syncthing is about seamlessly syncing files with devices you own, not file sharing as such, it does a good 98% of what this program offers with a more open source background and is completely free. I share files, what, once a year? Syncthing works great for that use case. If I want to share files too big to email, I can stand to upload to Onedrive/Dropbox/an open directory on my web server for that one-…
Oh I wasn't arguing in favor of using this. I doubt I'll ever use non open software for my data again. Just saying I've run into problems trying to use syncthing for sharing files.
I believe you when you say you've had problems performing file shares to arbitrary people, my comments were directed only that my use case is somewhat different.
Cheers!
