Intel notified vendors, (such as MS), so I'd assume the U.S. government would get these patches as well, I would also guess that any large customers of intel, (including the Gov), got some level of advanced notice, just probably not before any other large customers, which I do not see a problem with.

intel want to be able to operate all around the world and not be forbidden form non US markets if it is seen that they directly pass an exploit to the US gov so that US gov can use it to exploit into other nations systems then those other nations will ban Intel from sales. (even US allies would ban intel)

Who says they didnt?

Any such notification to agencies that matter would be classified information.

Now given that it’s Intel, the notification may have been “Reminder that our chips are working according to spec”, but I’m sure people knew.
