> Big companies are significantly better to work in when you're either (...)

You're basically stating that people who are hired to staff projects that are superfluous secondary moonshots are more likely to be fired than those who maintain core business areas. That's stating the obvious. When a company goes through spending cuts, the first things to go are the money sinks and fluff projects that are not in any key roadmap. This is also why some companies structure their whole orgs around specific projects and even project features, because management limits the impact of getting rid of entire teams by framing that as killing projects or delays in roadmap.
