Well tweets aren't legally binding, so chances are he's just outright lying so they can have their cake (DoD contracts) and eat it too (no bad PR)
companies like saying things that makes it look like they aren't doing anything bad but then they decide to do exactly what they said they wouldnt
e.g. google project maven, microsoft hololens (military), and much much more
This is so funny to me. Especially since Elon musk had to buy Twitter due to his tweets.
> Well tweets aren't legally binding
There's nothing in general about a tweet that makes it any more or less legally binding than any other public communication, and they certainly can be used in legally binding ways. But sure, a simple assertion to the public from the CEO of a privately held company about what a separate contract says is not legally binding - whether through tweet, blog, press release, news interview, or any other method.
