@sposadelvento @pluralistic Thanks for mentioning FairScan! (I'm its developer.)
What's funny to me is that Wired published an article earlier this year highlighting FairScan as an alternative to the enshittification of software, using the very term popularized by Cory Doctorow:
"FairScan is like that, which makes it stand out in an increasingly enshittified field."
