If a mistake I made resulted in thousands of people losing their jobs who wouldn’t consider it? At the very least I wouldn’t lie about “taking responsibility” if I had no intention.
The only mistake was hiring too many people in the first place, way way beyond what was really necessary. I suppose that gave them false hopes of being forever employed by Fb, aka millionaires in the making. I know being fired stings like hell, but it just a job, a limited time contract. Hopefully some good startups will come out of this whole situation.
