No. The main reason people are worried about what happens to Valve when Gabe passes is because Gabe is the owner, he owns more than 50% of the company. Valve has done well under him but once he’s out the picture and that more than 50% ownership is transferred to another person then who knows if the company will stay the same. After all that 50 makes the decisions about the company
If that 50 was split between the workers there would be less certainty about the potentially passing of ice person because the workers collectively uphold the company vision.
