Honestly, it feels like you're just bitter and stuck in your ways. Yeah, git works. Syncthing works. Syncthing also has non-obvious behaviors that can lead to you wiping your folder and losing all your data (source: I've done this accidentally). These things take a lot of effort to setup and keep working, and a lot of fiddling over time. There are plenty of people out there who just want something that works, that doesn't take up valuable time and mental bandwidth. Fig is great. Maybe not for you, but it seems to me like you're simply not the intended demographic.
