While that's a lovely idea, are there actually any such applications that actually allow you to do this? When even Skype and Skype For Business don't work together, how likely is it for programs made by completely different companies to do so? And whatever your views on the competence of the UK government, expecting them to produce and implement a global videoconferencing standard and get all of MS, Apple, Facebook and others to start using it on a timescale of a couple of weeks during a global crisis would be a little unreasonable. However you think the internet and videocalls should work, right now people have to deal with how they actually do work. Zoom may or may not be the best choice, but picking a single system to run things on was certainly the only sensible choice.
