That's why I have advocated tools like Fossil to other members of our Hackerspace and other communities like Pharo or decentralized options to Mozilla Science (without much acceptation in the communities or even any reaction from Mozilla Science).
Going with the de facto and popular defaults (without caring about freedom or diversity) seems the position of open source/science communities and even digital activist, which contrast sharply with their discourse for the building of tools/data/politics, but seems invisible in the building of community/metadata/metapolitics.
The kind of disempowerment these communities are trying to fight, is the one they're suffering with GitHub, like showed here: https://hypothes.is/a/AVKjLddpvTW_3w8LyrU-
So there is a tension between the convenience and wider awareness/participation of centralized privative platforms that is wanted by these open/activist communities and a growth in the (over)use of the commons that is bigger that the growth of its sustainability/ethos, as shown here: https://hypothes.is/a/AVKjfsTRvTW_3w8LyrqI . Sacrificing growth/convenience by choosing simpler and more coherent infrastructures aligned with the commons and its ethos seems a sensible approach then.
