I agree. The are part of the state. They are a standalone company, but wholly owned by the state. But other aspects of the state (eventually) reacted to the injustice: MPs, select committees, ministers, the public inquiry, and hopefully next the legal system as some of these people should be in jail.

> But it's an older term than that.

Fine, I’m happy to accept that. Just like I’m happy to accept that R&B has nothing to do with BB King any more (well, actuality I still struggle with that).

Definitions and usage change. The current usage is the one that matters. Not the legacy definition.

When the original poster wrote “massive deep state cover-up” I think the implication is that shadowy figures throughout the state are pulling cover-up levers, when it was one privately owned company and one publicly owned company. The rest of the state moved (albeit slowly) to expose this and make it right.
