I think that's the problem, they are still signing up on a centralized websites like the one owned by Microsoft (ie. Github) and have to push commits there.
You do have the ability to use Github without revealing your identity. I believe developers using Tails OS can code conveniently. What tools do you require? Programming software can be stored in persistent storage. Each commitment is automatically submitted through Tor.
This is a requirement for any developer who chooses to enhance anonymity nowadays.
To get rid of that centralization, we need a decentralized platform that offers all of this not just a place to store PGP keys.
Not to mention that storing PGP keys inside a transaction does NOT solve anything whatsoever.
Does this have to do with Saylor's new decentralized identity proposal? Yes, it's just PGP, but more complicated.
