I was using WebEx for the longest time and our company switched to zoom. I recall that it was only for price and that there was a lot of missing functions that our team was used to.
YMMV with all these examples. There have been multiple times where I have emailed a utility bill or signed lease. My insurance has an online portal to change my car or house insurance (sorry I don't have health insurance).
I get it though. This basically comes down to companies that suck and still use fax machines.
Everything's technically a rental. Nothing lasts forever. That console probably will stop working eventually.
