What is the meme? Also, what is FOSS?

Edit - I’m guessing it’s free open source software orsomething like that, and the meme is that sync is not open source!

Why have you posted a blank comment?

The first one is towards the very last days of the free Reddit API calls so the mass exodus began, the second is probably around the time all the apps were getting finalized for their beta versions of Lemmy - like sync.

so why should I pay for it?

Did someone say you had to? Or that you even have to use the app?
