>top level of government just needs to make the declaration: as of X, all Microsoft licenses will be terminated. No exceptions. Adapt or die

This is unrealistic populism. The type that gets upvoted on HN, apparently. It's not possible to just ditch all Microsoft licenses in a year, or in 5 years, or in 10 years. There are hundreds of critical systems that can't just be migrated to Linux overnight (or ever). And "just dying" is... not an option for a government branch. What is this even supposed to mean.

But we can limit American bigtech by 90%, and we should. Especially everything in the cloud.
