You're making it sound like this is commonly practiced and a standard procedure for the DoD, yet according to Anthropic,
Designating Anthropic as a supply chain risk would be an unprecedented action—one historically reserved for US adversaries, never before publicly applied to an American company.
Some very brief googling also confirmed this for me too.
Everyone is fixated on the name of the rule (and to be fair: the administration is emphasizing that name for irritating rhetorical reasons), but if they called it the "DoD vendor exclusion list", it would be more accurate.
This statement misses the point. The political punishment to disallow all US agencies and gov contractors from using Anthropic for _any _ purpose, not just domestic spying, IS the retaliation, and is the very thing that's concerning. Calling it "DoD vendor exclusion list" or whatever other placating phrase or term doesn't change the action.
