I think you misunderstood what people are taking issue with. You explain that this matter is complicated and non-trivial - and yes, that’s exactly the point!

People don’t have a problem with real-time communication via audio or video in general. They have a problem with the suggestion that it’s a trivial issue that can be easily fixed by "jumping on a quick call."

The point about there being a "fairly in-depth" description of the issues isn’t that there’s nothing more to discuss - fixing those issues would obviously require talking through the specifics. The point is that this is a real problem that requires action and commitment, so suggesting it’s a non-issue that can be clarified with “a quick call” comes off as dismissive and unproductive, whether that’s intentional or not.
