There are more reasons to fire people than just financial ones. Perhaps some didn't bring the results, acted liked wannabe-stars among their colleagues, spilled company secrets, caused a bad atmosphere at work for whatever reason.
Yes, it is odd if they truly fired as many as 25 at one day. But perhaps Gabe just decided to sweep all those bad apples out in one session? Anyway, we don't know for sure. I just doubt that finances are the reason.
