Employee solidarity matters, but absent a legal constraint, I don’t think it’s a durable control.

If this remains primarily a political/corporate bargaining question, the equilibrium is unstable: some actors will resist, some will comply, and capital will flow toward whoever captures the demand.

In that world, the likely endgame is not "the industry says no," but organizational restructuring (or new entrants) built to serve the market anyway.

If we as a society want a real boundary here, it probably has to be set at the policy/law level, not left to voluntary corporate red lines.
