* Just let them keep doing whatever without delivering what they claim they can
* Create new moonshots for them just because
* Move them to other products, but that doesn't mean they'll create more value as an org with (now) double the people
So what ends up happening is re-orgs which actually mean shutting down some failed ideas, moving the high performers to other products, moving low performers out of those products, then firing people who were left without a team.
Plus you need to take into the equation an assumption that because of how things look right now, natural attrition will be almost 0 in the next year or 2. If you're used to 5% of people leaving on their own per year, assume its closer to 0% for 2023 and 2024
This is way beyond the cynical claim that this keeps the stock up for another 2 months before it goes down again. There are teams delivering nothing. There are teams delivering 90% of the companies income. You can't just decide not to fire anyone, move 100% of the employees to the 90% income team, and think that income will grow just because more people work there now
Now, do these companies do it right? really finding the good people and keeping them, and removing the weaker people, thats up to debate
