[Edit]: The form, at least on the respondent side, is usable (thanks @matt ). The general problem of huge lack of accessibility with most of these sort of services which are now being endorsed in lieu of 365/workspace is still very worrying though, IMO.

"Today we are very proud to announce that the United Nations has switched from Google Forms to CryptPad Form for collecting endorsements on the UN Open Source Principles: "

Welp, guess blind people are left out of that too! If CryptPad Forms is about as accessible as their documents, sheets and presentation editors, we're well and truly fucked. But it's like, great. And open-source. And respectful and encrypted. And good. Just plain good. Accessibility just, isn't one of its features. Oh well.
