yeah, its hard to predict what will happen to it, especially after gabe steps down or dies, but depending on how much of the company is broadly owned by employees vs individuals, it can help to shield it from bad decisions. Unfortunately, we don’t know the exact numbers. If gabe + mike own 51+% then it could potentially lead to overriding employee will in a bad decision for money (either through their actions or through inheritance like you say). Or the employees could just collectively make a bad decision too.
Since the 70s. It was in an act signed by Nixon.
