@thomasfuchs sounds like all we have is anecdotal evidence then.
And to be clear: I’m not some uncritical Mastodon / Fediverse fanboy. I have my own concerns about the technology. I just happen to have a lot more faith *generally* in open source/standards/protocols than I do in *any* corporation or techbro “luminary” (whether that’s someone who seems relatively harmless, like Jack Dorsey, or someone who seems seriously unhinged, like Elon Musk).
