And it is possible there may not be any firings at WotC. This is the only well performing part of Hasbro.
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.
Then that is kind of fucked up. WotC is the part of the company keeping Hasbro afloat right now. Activist investors had wanted to spin off WotC because the rest of the company is performing that badly.
Firing from WotC makes no sense.
