But is that really a "sign this or be dismissed" threat? It seems more like a "Company X is dismissing you. We (Company Y) are offering you a job. Would you like to accept?" type of situation. Which is a lot better than a "Company X is dismissing you. We (Company Y) are not interested in you either. Good day." type of situation.

RIght; in fact, in my last job, it happened in exactly that way. A 2nd or 3rd rate Beltway Bandit got bought by a big foreign company, and because of the latter any units working in national security had to be acquired by a US company, and before the acquisition. My unit was one of those, and we got a document with a bunch of demands, like the last N years worth of non-competes you'd signed, and then in theory they'd hire you. If you didn't sign it, you'd be laid off (in this case there was a successor organization, that wouldn't be true in these aquihires).
