And I'm saying that if everybody is using unreliable tools, especially mandated ones, then it's not particularly backwards. E.g., during a consulting gig in Manhattan, it was not uncommon for a subway failure to cause the majority of people to be late for the first meeting of the day.

Similarly, I've seen a few companies where it's just assumed that a 9:00 meeting really starts at 9:05, so everybody has time to travel from their last meeting. I think the videoconference nonsense is effectively the same. It doesn't really matter if you designate 8:57-9:00 as your "make sure your tools work" time or 9:00-9:03. It just matters that everybody has the same expectation.
