“In fact, a screenshot from Kearns’ mobile phone reveals that while his account had a negative $730,165 cash balance displayed in red, it may not have represented uncollateralized indebtedness at all, but rather his temporary balance until the stocks underlying his assigned options actually settled into his account.”

How the hell is this a thing? Who approved this UI?

It isn't a "UI" decision, that's an accurate reflection of the value of the account at that point in time. How would you reflect a future date's strike price without knowing what that could be? You cannot.

The problem isn't the "UI" the problem is that people are options trading who have no business doing so. It is actually incredibly complicated, and some gambits people are making even more so.

I've read up on options, but I don't do so because I know enough to know I'd need to full time study it for up to a year and then dry-trade to test my assumptions.

It's not that hard of a market but it is a market with a higher risk tolerance than the average investor should tolerate. Most people that trade in the market know you are negative till the other trade settles. You are right it is not a UI issue, the UI reflected the current state of his trades.
