if they want they can fork lemmy and do their own thing. heck who tf cares if lemmy has a communist dev, you can selfhost it ffs. no one fucking cares.
The design of social software is never apolitical and problems with many open source projects boil down to liberal misconceptions about how governance of their project needed to work. The devs being communists is cool and good.
They’re literally getting pissy because the devs won’t build a block of hexbear into the software itself. Great liberal values. (And an incredibly poor understanding of how FOSS development works.)
