There's an even bigger over supply of labor now more than ever. So, META is using this to their advantage. The author states that this strategy is short sighted and will show future attrition from Meta because eventually the industry demand for SWE will recover. I'm just not sure about that last part. Musk has shown that you can profitably run a software company with 80% less staff. I would imagine other companies will aspire to this goal as well, especially now that the days of crazy growth are over. We're no longer in a growth economy anymore.
EDIT: I have not confirmed that X is profitable. And I don't know their numbers. but, I assumed after laying off 70 to 80% of staff, it probably should be right?
