There's a lot of siloed misinformation here.
- it's not because of a slowdown in the industry
- It's not because of poor game releases/sales.
- It's not because companies grew too much/quickly.
FURTHERMORE...
- It's not just gaming.
- It's not just IT as a whole.
- It's everywhere.
This has nothing to do with performance or the economy, and everything to do with late stage capitalism. Companies have a round of layoffs just to bump up their year end statements. Worse yet, they then proceed to hire people back for less money.
It's money-grubbing evil, no more and no less.
