I go out of my way to use American services. It would be hypocritical of me to deny others the right to use their country’s services. Plus competition is always better for consumers so have at it.
A lot of this discussion actually more about "use baremetal" or "put servers in your closet". HN tells Americans to do the same thing (and hire them to do it).
I am deeply troubled by what the Trump regime is doing but I think this trend for European countries to use European tech is actually quite good. Competition is better, plus your privacy laws are much better. I host some of my own data in Europe for this reason.
