Internet messaging is so broken that FB alone owns 3 incompatible apps. Google has *6*, not counting the ones they canceled: https://arstechnica.com/gadgets/2020/05/google-unifies-messenger-teams-plans-more-coherent-vision/
@tomosaigon FOSS's duplication of effort is nothing compared to proprietary software, which reinvents every wheel with new proprietary protocols clients and servers every time and when they inevitably abandon the code, it is just thrown away.
All those distros are sharing a LOT of tech, protocols and code between them and there is a lot of compatibility between them. The differences between them are small compared to the similarities.
@kyle the proprietary software you talk about reuses lots of tech, lots of existing (open source) software, lots of servers. It's definitely comparable.
