I just realized that I've been using Syncthing and have never donated. Done! Other recent donations to essential orgs and #FreeSoftware builders/maintainers:
EFF (membership, first time)
Mint Linux
Trisquel Linux
Signal
Wikipedia
Ozark Regional Library (my peeps!!)
PBS
Upcoming:
The Document Foundation/LibreOffice
FSF
InternetArchive
Except for memberships I only donate $5 at a time but do this several times a year for each one as much as I can afford.
You?
