In my opinion, if you want to have a real impact, it is probably more effective if you buy European things instead. My arguments are:

1. American movies and music also push the American narrative onto Europe and acts as propaganda
2. If you pirate stuff like Windows, you will automatically subject to American control - since they decide what software you can run on their operating system and what stuff you see in the Microsoft store. Therefore I would claim it is better to switch to Linux in that case. This is true at least in some way for a lot of software, including Office365, Apple stuff etc.
3. If you buy European things you directly support European companies, which then have more money to create new products and they get better chances in raising money from investors as well.

Russia

lol Russia is not particularly popular here right now, we are even on their list of “unfriendly countries” if you didn’t know.

I am Swiss myself and I feel like things are changing since Trumps second term, at least my friends seek closer ties to Europe now.

Proton gives me a bad feeling in the stomach, I would encourage people to not trust it. The guy is either a big Trump fan or most of his customers are from that base. The best option for e-mail is selfhost + pgp, the second best option are the various small companies offering email all across Europe.
