A recent article from the Economic Policy Institute notes that CEO pay slumped slightly in 2022:

CEO pay is linked strongly to the stock market—and market declines in 2022 led to an uncharacteristic dip in CEO pay…

CEOs are getting paid more because of their leverage over corporate boards, not because of contributions they make to their firms.

Another site calculated the average decrease:

[I]n 2022, CEO pay decreased 7.3% and 2.7% for the overall Russell 3000® and S&P 500® indices, respectively

And yet, the Mozilla CEO pay has risen from $5,591,406 in 2021 to $6,903,089 in 2022. That’s a 23.5% increase.
