Sorry for the second reply, but I did some digging and found two things:
1. Apparently, David Gabriel got into some controversy a few years ago for implying that the reason sales were down was because of diversity. Though FWIW, I think that's basically what his job entailed: looking at sales and figuring out what works and what doesn't. Those types of decisions will likely still be made, just not by him anymore.
2. We've got at least four more notable names that have been laid off, but before anyone asks: no, none of them are Nick Lowe or CB Cebulski.
Details of three editors at Marvel Comics who have been laid off this week, as well as the Communications Director
