Do I agree it's incompetence. Sure. I think someone who was competent would have said "hey that going to make this fail".
Nobody broke anything out of hubris. Every transaction will go through.
What you are watching, is actual change. And yes, shit happens during major change. Not all of it great, but instead of 4 years of pass the puck from side to side government, we are going to see change.
A portion of what I do involves companies switching to our computer systems, it's very common for there to be bugs during that process, maybe that's why I'm understanding of this.
Again, I could understand how this stressed people out and someone "had a really shitty day"
If you were a CEO you have been around the block enough to understand shit can happen during a transition process though, and that isn't to say someone shouldn't get an ass chewing or worse.
