Where in the terms of service did you find that? Afaik Proton is subject exclusively to Swiss law, as a result of being based in Switzerland.
@Tutanota @protonprivacy This is some stupid challenge. You had the initiative to post the list and they complained/commented that Proton mail was not included. It’s within their right and they are correct, Proton Mail is the only product that can be comparable to Tuta Mail.
You guys are competitors, not enemies, and should be focusing your energies on improving your own services instead of this. For the record, I use both Proton and Tuta and I am happy with both.
