Actually I'd invite the FOSS developers to learn from UI of sync. If they get better, I'll switch to FOSS apps, I'd contribute to FOSS if I had the time, but I don't and their UI does feel unpolished. Used liftoff and jerboa before sync.
Perfect response. I not usually one who is made fun of for being bougie, but why not pay for an app that I've used for nearly a decade and can easily afford?
