No, everyone (bar one person) has the same native language. The person with non-native English does not care, and often has their camera off as well.
The 'issue', such as it has ever been raised, was "why don't you have your camera on?", and in one case it was "I have no camera", and in another case it was "I'm walking around, you won't see me or you'll get dizzy trying to look at me".

I'm not sure how much I actually want to spend time 'collecting candid feedback' vs a) getting stuff done and b) supporting other people in getting their stuff done. Camera on/off has not been noted as enough of a hindrance (as in, any at all) by anyone as an impact on their ability to get stuff done. We also have phones and direct meetings where people can collaborate that way.
Forcing "cameras on" is... the covid-era version of "butts in seats" it seems.
