I didn’t know them and it was a very interesting read. As other user have said, my experience in Mastodon has been very different to theirs. And, indeed, they are responding to their area of interest: privacy. However, if you go there with the political aspiration of not contributing to big data collection in the service of ads, that’s a whole different thing to be on the lookout for! Still, I admire their work. Thanks for sharing this!
