Interesting, last time I experimented with creating a Proton Account I met this issue where I was obliged to either use a Mobile Phone number as verification or to abandon the process entirely. I did not know of this pretty recent article.

Which apply to most modern website. And this part isn't surprising since they have their own CAPTCHA system[2].
I have to agree, only up to the point where Proton advertises themselves in various ways that attracts a specific type of Customers. Almost any where you look on their website, they advertise themselves as the Service that frees you from the Big Tech.
Many email services, citing security reasons, require a phone number for identity verification. This creates an unfortunate paradox in which you must give up a highly sensitive piece of personal data to Big Tech.

Choose an internet where your privacy comes first
With Proton, your data belongs to you, not tech companies, governments, or hackers.
https://proton.me/More importantly, on the front page they mention this,
Most tech companies, whether it’s Google or Apple, define privacy as “nobody can exploit your data except for us.” - We disagree. We believe nobody should be able to exploit your data, period.
Java Script is a deal breaker for me. Even if it is as Private and Secure as they make it seem, Java Script being mandatory is instantly a no go. It can be exploited, so the entire 'no body should be able to exploit your data, period' argument falls short in my eyes.
I am really skeptical about Proton generally anyway. The motive of the entire project is a question mark for me. They had scandals and controversies in the past too which further raised more questions for me. They promised they would not hand out any IP to any body and then they handed IPs for a case of the Authorities and after being under fire for it they deleted the statement from their Policy. I find it very suspect to have a project that 'promotes Freedom and Privacy' not being subject to a lot of hatred from Governments. It is being praised even by the United Nations.
Fishy if you ask me.
