Why would you want another year of their software for free? This is their second screw up (apparently they sent out a bad update that affected some Debian and RHEL machines a couple years ago). I’d be transitioning to a competitor at the first opportunity. It seems they aren’t testing releases before pushing them out to customers, which is about as crazy to me as running alpha software on a production system.
I’m sure you have reasons, and this isn’t really meant to be directed at you personally, it’s just boggling to me that the IT sector as a whole hasn’t looked at this situation and collectively said “fuck that.”
I’ve been using Syncthing-Fork (on F-Droid) for the extra features it has. I wonder if that developer will be able to continue.
