It's a privacy activist stance, privacy and security are always at a constant battle. There was a post about it a few weeks back, every attempt at security compromises privacy, because private info is the easiest way to lock security down, so it's always the route that companies take. Personally I don't think a corporation should have to risk their company over it, but I don't think a company that isn't privacy oriented should pretend to be. It's misleading. I give them credit that they might be good for privacy but, the entire operation gets undermined when in order to sign up, it tries to force you into giving information that could identify you. The less information needed the better, and the less you can tell overreachers. If you don't have the information you don't have the information. That's signals motto, it's also Mullvads motto, and its the direction that proton runs in if you can find your way through it's hoops.

Can you tell me which endpoint/region that you used? Cuz I just tried using a VPN endpoint from Switzerland Sweden and Ukraine and all three of them brought up a requirement to have a verification email

edit: disregard apparently it was a browser issue, switched from Firefox to Chrome and reconnected to a Switzerland endpoint and it let me solve a captcha instead of using email verification system
