I mean that's pretty standard for a McKinsey ghoul:

• Step 1: go to an ivy league college, get a business degree
• Step 2: work for McKinsey for a few years as an associate
• Step 3: get a job at a McKinsey client leapfrogging everyone else into management/c-suite
• Step 4: hire McKinsey to bring their arrogant children into your org and screw things up

Everything about her subsequent career has been going from one upper management/c-suite role in a tech company to another. This is not the resume of a person who should be running a nonprofit that controls the most important open source project on the internet. But beyond that just look at what she's done in her one month at Mozilla:

• 1. Massive round of layoffs
• 2. "Focus on {buzzword}" where {buzzword} in this case is AI

That's straight out of the McKinsey playbook.
