The FAA issued a mandatory airworthiness directive as a result of this crash. Boeing didn't include training for a new anti-stall automation regime in their type cert update class for existing 737-rated pilots moving to the 737 MAX. There was apparently a malfunctioning angle of attack sensor, which caused a software data conflict which caused the anti-stall assist (which the pilot wouldn't have known existed) to repeatedly trim the aircraft nose-down.
There is also the possibility that a separate pilot assist system read a possible near-stall and enforced difficulty in pulling back on the stick (to prevent what it saw as a potential stall). So the pilot couldn't pull out of the dive that the MCAS (trim changer) had caused.
The blame for this incident does not lie on the pilots failing to RTFM. Boeing changed several systems without telling anyone. Now the plane's been type rated, so software changes to fix it are significantly difficult.
Imagine Boeing as a guy saying "Screw those idiots who operate our multimillion dollar safety-critical product; they're too stupid to know how to work it!" This is a closer perspective to the truth than the parent's comment.

If this is accurate, it's beyond criminal. If they're putting pilots in planes with automated systems without any knowledge of those systems, let alone how to operate/override them, someone needs to be behind bars and is responsible for the deaths of those people.
