They have doubled down officially with their official Mastodon account https://mastodon.social/@protonprivacy/113833073219145503 I therefore consider this official opinion of Proton. Focussing on one aspect and completely ignoring the bigger picture of a luming fascist period in the most militarized economy of the world is just inacceptable. Proton just could have kept their mouth shut, but they decided not to.
Check out Posteo. They are awesome.
