Personally, my biggest problem with the proton CEOs actions, is that he doubled down using official proton social media. This went well beyond a “personal opinion” and made this sound like a position the company held.

I managed to find this from the official reddit account: https://www.reddit.com/r/ProtonVPN/comments/1oj8u5y/the_official_proton_vpn_commandline_interface_cli/

It’s “early access” still, but publicly available.
