Yup! And that leads to situations just like this. I'm not saying it's right or wrong. I'm just saying that people who depend on not being surprised by stuff like this prepare for stuff like this because it happens, in whatever form it takes.
Yeah, I was seeing some of the tweets claiming that conferences had been cancelled over it and I can't help but think "good, maybe they'll learn to be more paranoid about critical projects". Though I assume it's 99% hyperbolic.
To have this be a business blocker, they clearly not only don't have any other standard tools available to prevent this display issue, but they also upgraded their OS, can't roll back to an earlier backup (probably don't have backups), and did all this on the machine used for the presentations, without any alternatives.
That's a shocking lack of care and they deserve to receive flack for it. You test that kind of thing well before the event, and then you do not touch anything. Least of all upgrading the OS. I can't help but assume that these people are just using their personal laptops and hoping for the best on the day of an event. If they are, a small orange dot is the least of their concerns, and serves as a nice canary to their employer.
