Syncthing has reminded me how great computers can be if they are not made by corporations. It’s simple, predictable, sane, acts no-nonsense. You can configure it however you like and it always keeps you in control. It’s a pure function and it’s good at that. It’s free and open-source, but I’m much more happy to donate them €10/month than e.g. Dropbox. I would be a much happier person if at least half of the programs on my Mac/iPhone were like that.
