Sync is fine. I used it on Reddit, I think sync has its place, and it has good features. I don’t know if I would call a user base a cult, people are allowed their preference for an app - point and case, I used it but switched when I found something I liked better. I think it is okay to get paid for something you spent time developing, but I also support FOSS. I don’t quite know what you mean about vegan apps so I can’t really comment on that.
