There is one job as old as the human race, and even though there are machines now, they will never be able to fully replace humans.

Are you trying to solve a technica, or political/moral problem? Let’s Encrypt doesn’t create, see, store or log your private cerficates. So, even if they are in the US, I don’t see a risk, and otherwise, the other parts you use in general are probably vulnerable to the problem even if non-US.

For ex. the US could simply order browsers stop validating any certificates not issues by US companies in browsers. And whoosh. Having a non-US certificate won’t help much there either.

You can’t demand anything from open source becasue I can just change the demands myself. Linux is free from this nonsense.
