I'll note one thing that was quite annoying on my locked-down browser (via uMatrix): The site appears to be unscrollable without loading scripts from (probably, not spending the time to investigate further) typeform.com or subdomains of it.
Maybe it's just me, but I think having third-party scripting whose absence breaks fundamental features is poor planning.
This is nice but I'd also like some kind of detached evaluation of how well they function in practice, in terms of pros and cons. My sense is that in the videochat/conferencing area there's a big difference between feature offering and how well those features actually work at any given time.
