The article notes the increase in pay and states

> Mitchell Baker, Mozilla's top executive, was paid $2.4m in 2018

but doesn't offer any consideration or speculation as to why this is exaggerated. It's entirely possible that without that particular exec, Firefox would have been even worse off, or would have taken another direction with regards to privacy, etc.

My subjective feeling is that $2.4m does indeed seem too high for such a position. But I have no objective data to support or refute this. It's quite possible that the same person managing a comparable employee base at a FAANG would earn even more.
