It's worth pointing out that in a standard stakeholder-owner/management relationship, these layoffs are exactly what stakeholders WANT their proxies (ie - company officers and board) to do. They raise stock value, or at least keep it stable if revnues are falling. Improving stock value is the job description of the officers and board. That's it. Not preserving human equity. Not even providing quality product.
This is not my defense of the corporate model, by the way. Just my observation. In my experience, the dissonance we feel that focuses so heavily on the corporate officers and boards is often (not always) misplaced. The real culprit is impersonal, and hard to direct blame at.
Street-level employees typically work at a company like an RPG company (as distinct from, say, fast food) because they have some desire, or passion, for what the job entails. They write, and design, and work like demons, and have a ball doing it because it's what they love.
The officers and board have little to nothing to do with any of that. What they do is largely accounting. They work in a world of numbers, where every staff member; every paycheck written, is a financial liability that reduces stock value. The odds are strong they don't know anyone by name outside their own circle. The employees are represented by a set of statistics that compare their value to the company (frequently very hard to quantify) with their liability to the company (very EASY to quantify).
Under those circumstances, it becomes easier to see why great people are laid off. It is, as the mobsters say, "just business." The owners of the company, the stockholders, are completely removed from the actual people who make the company run. Or, to put it better, from the labor that makes the company run. They don't know, don't care...they didn't invest in Hasbrow/WotC because they admire the work of Monte Cook and Ryan Dancy. They invested because its performance, by whatever metric they chose, looked good and they want a piece of that pie. In short...accounting.
The model is very effective at collecting large amounts of investment capital, which in some cases is an absolute requirement for a new venture...but it results in the schizophrenic, quasi-psychotic kind of corporate mentality whose pitfalls are well documented.
And it's why good people are laid off at Christmas.
