Disclaimer: MS employee/don't speak for the company etc; Yes, SDET has been (at least in my division and those I talk with) dissolved and integrated into SDE. I raise an eye at the parent-parent post not because of the impact this will have (certainly some of the concerns stated here echo strongly with me) but that it's been a relatively recent change and I'd be skeptical that you can attribute any recent failures to this specifically, things just don't move that fast. As to seeing how it pans out, it's certainly up in the air. As a former SDET there's a big wall to climb of making testability performance security etc. part of the first line of thinking alongside design and implementation.
