It's nice to have choices. Luckily, you have many choices for a lemmy app, unlike reddit.
Sync has a loyal userbase, and the dev has made the price point based on the number of lemmy users and what he needs to earn a living by working on lemmy.
If lemmy had as many users as reddit, then the price would be lower. Sync is also in beta.
You don't get the hype. That's fine, you don't have to.
I'm just glad lemmy has an open api and we have many choices.
