Being seen is consequence of working in a physical space, not the objective. Not unless you're a stripper. Phone meetings worked just fine for decades, video chat is pure narcissism.
If there were somebody deaf on my team then I suppose I would reconsider it, but there isn't, so spare me the moralizing.
I'll be honest. I'm that guy with the hearing accessibility issue. That's why I'm mad about people who refuse to be seen.
If we use MS Teams or Google Meet, then it's mitigable because those support computer generated captions (albeit not perfect). But other technologies like Zoom, Webex, etc. don't have that feature, so literally, if there are no captions and I can't see you in order to lipread & read some body language, then we are unable to have a productive meeting. You might as well be speaking a foreign language.
Even if everyone has normal hearing, it's still a good thing to be able to see each other to check-in on everyone's body language and well-being. If someone looks really unhappy or looks like they're not taking care of themselves at all, then this is information that they need help with something.
