Honestly, it's a solid and fair question of labor to management. If they're going to be changing incentives, an employee is in the right to ask about related incentives so that they can make the educated decision sooner rather than later that "this place isn't for you," which was Zuckerberg's stated goal in the Q&A.

The door swings both ways, and if Meta can't exist without making people work harder for less compensation, maybe Meta doesn't need to be in the market. More information shared earlier can optimize everyone's time.
