Not hating on open source, just let people use what fits their expectations and needs and stop deterring them with gatekeeping :P
UX = user experience
But for a lot of people this is the best alternative. As I mentioned in another comment, people will generally pay if it gives them a good experience. I used Jerboa up until now but it did not have an easy UX like Sync has had. So yes, functionally there are alternatives, but in terms of ease of use? Sync is the best I’ve seen.
To be honest yeah that’s fair. No one is forcing you to get the license and from what I read in this comment section, the ads are minimal.
I only replied because your earlier comment sounded like you were patronizing someone for not being able to spend $20 on a lemmy app.
