The beatings will continue until morale improves.

When will they acknowledge that the Metaverse sucks and that Zuckerberg needs to go?

They will just slowly lay off the metaverse teams and then we won't hear about it as much and then never again.

Doesn't Z still own a controlling amount of voting shares?

This is how it's acknowledged. A company does not communicate mistakes directly because that would reduce shareholder value.

If the layoffs are in the “metaverse” units. If they’re not then aren’t they just doubling down?

It looks like they don't acknowledge mistakes at all.

Never: Zuck owns the company (he owns a majority share), so he can't be forced out.

Zuckerberg cannot be fired by the board like, say, Elon Musk can be at Tesla. He is a 50%+ shareholder.
