Yes, they do, I’m saying they could avoid US payment processors if they wanted to w/o really any change for users other than maybe changing the credit card they use to avoid the foreign transaction fee. That was the whole thrust of this comment chain.

I think Tuta does that since I’m charged in euros and subject to foreign transaction fees, so I doubt they pay US taxes. It’s no big deal, I just use a credit card w/ 0% FTF and I’m good to go.
