Is it expensive for ad removal? Yes.
Is it too expensive? No, for me personally no. I wanted to support the dev and I did it. Also It's the only app I am going to use until Lemmy is no more.
Okay, I won’t push you from Sync. But if you have this sort of money, please consider supporting Lemmy directly or indirectly (Mozilla, among other things, funded the effort to find and patch TootRoot before it became a problem).
That's how ad removal for literally every app in existence works. The ads aren't some kind of natural disaster that I'm paying the developer to "fight" lmao
