While “buy from EU” sounds reasonable (and it is, in terms of physical goods that shouldnt rely on huge travels around the world), it is dangerously intertwined with protectionism.

Politicians really like the idea of protectionism, but it doesnt help in terms of software, which is a big topic in here.

Open Source / Free Software is always global, doesnt discriminate against contributors from any country (may it be sanctioned or not).

I know a lot of really shitty proprietary software from the EU that I would always trade for free software from a global community.
