They've already paid what Billet requested, hopefully they also get some publicity out of this to help with the nonmonetary damages as well.
It's clear that it wasn't done maliciously, but there must be something seriously wrong with their processes for this to happen in the first place. The other comments they made were just adding insult to injury.
Edit: To clarify, they claimed to have accepted a quote that Billet sent them according to Linus on the forums. This ended up being a lie according to Billet.
