Pretty much. Everyone else will be able to trade with the east and southeast Asian countries business as usual. Maybe even more now that the US is making themselves less price competitive. The bad thing for the EU could be the drop in sales to the US not being replaced fast enough outside of the US leading to squeezing existing customers for more cash or possibly some businesses failing
I’d say try Linux. Ubuntu or Fedora and you’ll realize how much of your computer usage is based out a web browser and it doesn’t matter whether you have a Linux, Mac, or Windows computer
Email you’ll be stuck with some corporate entity that won’t be 100% open source. Running an email server and your emails not being filtered is a pain. I use Proton applications for email, VPN, and Dropbox type service. They have a calendar but hard to beat google calendar
Signal for pretty much texting. I actually have around a dozen people I primarily message through Signal so it’s viable for me
Matrix/Element for something like discord.
Onlyoffice, Libreoffice, or WPS Office instead of MS Office. WPS may not be open source
Browser use Firefox or Firefox forks
Krita, Darktable, GIMP for image editing
KeepassXC for my desktop password manager and whatever is available on Android
Maps you can use Organic Maps
Video editing i use kdenlive
Really emphasizing to the world that the US is run by bunch of idiots
