I don’t know about doing good or harm but I’ve used sync for reddit for years and years. The dev isn’t some big corporation and that’s generally enough for me. I’ll support them as long as their app has the experience that I prefer. I tried a few different apps until sync came out and I really gave them all a fair shot but none of them felt right. The fact that so many users bailed to Lemmy because Reddit broke third party apps and then turned around and got up people’s butts for using specific third party apps is kind of hilarious to me. A huge wave of users came here for sync etc and people are trying to push them away or bully them like reddit did? They might not be bullying for the same exact reason but it’s got the same vibe imo.
