Yes, what Boeing is saying is that MCAS, being designed to force the new plane follow the flight envelope of the old plane

1/ wasn't an anti-stall system

2/ and therefore wasn't a "security" feature (and therefore, it was completely ok to sell upgrades to that system as expensive options)

During a recent interview, Boeing CEO repeatedly said that no specific training was necessary on MCAS because MCAS is part of the whole plane, and when you're flying the MAX you're using MCAS.

This is indeed the problem: they couldn't even consider MCAS failing -- even as a thought experiment, because if MCAS fails, the MAX isn't a 737 anymore!

It looks like they locked themselves up into an alternative reality that they couldn't escape, until planes started crashing into the ground.

A bit tongue in cheek, but it's been shown that, when MCAS fails, the 737 MAX can't really be called a plane.
