Three of the four MDN engineers are still there, but their manager and all of the tech writers were made redundant. It's a damn shame, but it's not dead yet.
Documentation with no writers maintain it is pointless. It will quickly become stagnant and cause more harm than good
No documentation is often better than outdated documentation.
What I can't figure is how much browser core debugging will suffer with DevTools no longer available to inspect misbehaving in-the-wild JS/HTML/CSS -- code that behaves "right" on Chrome but not FF.
