It's also not necessarily a disadvantage. The real argument is that people management is important. Everyone from the new person who just joined to the decade long senior engineer need to be held to high standards. Which brings me to my next point.
The big problem with Twitter was management. Dorsey was barely a CEO for many years. Parag didn't seem to want to try anything. I think people routinely underestimate how important good leaders are. "There are no bad teams, only bad leaders" comes to mind. So far Elon has shown himself to be terrible in this regard. With SpaceX and Tesla he communicated a vision, with Twitter he's communicated very little and just instituted chaos.
