Anthropic isn't preventing them from managing their key technologies. If my software license says 1000 users, and I build into the software that you can only connect with 1000 users, is your argument that the government can no longer manager their tech?
That my software should allow license violations if the government thinks it is necessary?
I worked in defense contracting looong ago, so this is old news: when software is purchased by DoD or Govt generally, FAR compliance notices make it a license, not a sale of IP.
