In the linked speech Swen says:

I also want to thank @Wizards_DnD and specifically the DnD team for giving us carte blanche. I’m really sorry to hear so many of you were let go. It’s a sad thing to realize that of the people who were in the original meeting room, there’s almost nobody left. I hope you all end up well

Penny Arcade also had a post yesterday about hearing from former WOTC team members who have been let go.
