English is not my mother tongue and I really appreciate when someone's camera is on. Lip, gesture, any language cue is very appreciated in general, even for remote session. If someone's mic is shitty built-in one and camera is off, it's hard to focus TBH.
But I do agree that turning on camera constantly is tiring thing. I thought turning off the camera in the meeting can be considered rude but now I've changed my mind. I wish there were a middle ground for having a language cue in the conversation while the camera is off.
