Heh, I know. I bought Sync for Reddit originally, and was really conflicted about whether I should buy Sync for Lemmy. Was, like, "what the hell, I'll be supporting the developer."...well I'm glad I never bought the ongoing support things this developer offered! Staunch supporter of open source threadiverse apps these days, as you might imagine.
I actually didn't mind paying a monthly subscription to Sync for Lemmy, just to support the developer. He was super responsive at first and immediately fixed a comment sorting issue that I reported in his community.
Then he ghosted for a while and came back with a slew of updates. So I had hope that he would do the same again. Eventually after not being able to use Sync for a few months, I canceled my subscription. Would be glad to take it up again if he ever comes back and fixes it!
