Oh joy, I just love waking up to things like this.
First, my heart goes out to Laura. Seeing some of the stuff I've seen in this industry, I'm often surprised that anyone that's female or LGBT actually stays in it. That isn't to say there aren't some wonderful people, because there are, but it can also be a horribly offensive place.
I think it's good to tell Microsoft what happened that wasn't okay, but not right to crucify them. I doubt they expected this, and while they SHOULD have handled it better at the event when it happened, I also know full well how things like this can happen due to how chaotic live events can be. Hell, people can't even get proper set-ups for schedule appointments at smaller events, so not having the right people on-hand to deal with an event like this occurring doesn't shock me.
As for the comedian, I want to hear for sure that we know the right person (maybe that's been confirmed and I've not read it yet), but if it is, fuck him. Publicly shame him. I'm tired of the idea that people can pull shit like this and not receive any fallout over it. If he's going to get on stage and say something, he should be ready to answer for those words if they come back to bite him in the ass, and I've seen too many attacks on people who are trans to have much tolerance for it (beyond what is actual, unintended ignorance).
