Since FSFTN as an organization came into existence, mailing list served as a primary communication, announcement and discussion platform. As the organization started to grow in number of GLUGs and members, new requirements emerged for engaging more people.
One event after another, when more and more people were interested to volunteer for our activities, we asked them to join mailing list. But since most of new comers have already been captivated by proprietary platforms like Whatsapp, our first attempt was to bring them outside of proprietary and we ended up in favour or using Telegram Messenger.
Telegram messenger was not a complete solution, but it was the lesser evil that was convincing for those new comers to shift from a complete proprietary platform. Some of us have always tried to explain the difference between Telegram and Whatsapp beyond technical details.
With Telegram, the clients are FLOSS and the server is closed and proprietary.
With Whatsapp both clients and server are closed and proprietary.
Apart from this difference in clients and server being Proprietary (or) FLOSS, both these platforms are Centralized. Read why centralization is bad from freedom and privacy perspective. I think, now we should focus our arguments towards Centralization vs Decentralization along with Proprietary vs FOSS.
It looks like the team behind Telegram is not serious about bringing their server under FLOSS license and also they aren't focusing on decentralization / federation and so I think, we should start moving towards platform that promotes FLOSS + Decentralization + Federation.
XMPP have been giving us all the three for a long time and still they continue to do so. We have also once tried using XMPP and failed since they don't persist messages across sessions and federated servers.
This is why I bring Matrix into picture. Let's move to Matrix.
