It's just because that irks you when there are layoffs. But office supplies are assets, they're on the books and while they depreciate over time it's still something that can be sold and doesn't cost anything after you've bought them. The actual office building is different, since you generally rent it and the staff you need to pay monthly and you can't sell them to recoup part of the investment. High quality chairs etc cost a fortune, but they also last a decade plus in many cases. Still earlier this year they had 1000+ employees, that isn't sustainable for a game relying on donations basically. You need predatory microtransactions for that to workout which is of course part of the reason CIG monetizes in the way they do, they need to keep the boat afloat.

If the average salary is just $20k yearly were looking at a salary spend in excess of $20 million a year, not including offices or payroll taxes, benefits etc. And I imagine that the average salary is higher than that. If they are laying people off the reason is that someone in finance is putting his foot down saying this just can't go on.
