There will be consequences, they'll just take some time to set in. But morale is in the gutter across the company now, and a lot of people who would previously go above and beyond to maintain some level of software quality have thrown in the towel now, since this last round of layoffs, by virtue of who was targeted, very clearly demonstrated that the company doesn't actually care about any of that one bit, and the sole reason to perform is to ensure that you stay above the cut (and even that's hardly a guarantee when whole teams get laid off).
