I was visiting a buddy in Europe recently and he - and he claims many like him - have been doing this recently from a standpoint of no longer using US Big Tech products as appetite for both Trump's (though mostly: Vance's) perceived hostility towards Europeans, and US big tech being the main beneficiary of this behavior. He was the biggest fan of "just using MS products, because it's easy" in the past.

I still hope that this can evolve into something more agnostic to nationalism and less divisive. Just use the best product, and don't use cloud services if you don't need to; although switching from outlook to proton is a good move for privacy (allegedly, as I haven't reviewed server-side code), you're still relying on an online service for critical communications.
