Modus operandi in these companies is to rewrite/reintroduce whole products instead of fixing bugs from already discarded people. So if you lose a critical amount of worn out higher paid contributors, you just make a V2 or introduce a new product with a completely new fresh team that will get discarded after another 3 years. This requires fresh supply of motivated and hungry people willing to take sacrifices and a much smaller amount of people willing to exploit that.
