- Threatening lawyers

- The fair use update is reactive, and won't help anything

- Not separating microsoft/github from users of the platform (I agree the line is an worthwhile discussion)

- Not following up on the reasonable technical solutions that are being proposed

- Not seeming to ack that while the firewall ban might be the best they can do now, it'll block interested users of their own (GMP) library.

That said, the part in the GitHub reply dismissing GMP's hardware is also immature.
