Zoom making their software badly on Linux is 100% in line with the company. They aren't aiming for good design, they are aiming for the nontechnical user using out of the box windows or MacOS.
FWIW, the Linux version works fine for me, with a couple of niggles. The most annoying of which is that the software turns the headphone volume up to maximum at the start of every call.
No, it's not hard scientific data with a p-value. But IMO it's important to not simply write away all experience as anecdote not data without contextualizing the relevancy of the anecdata in question. I have seen way too many HN comments that look at usability and don't realize how specific their situation is that causes their issue. That and of course their complaints not being relevant/visible to the typical end user.
