No it's really not. Designing a system that changes the pitch of the plane automatically while relying on a single sensor that is known to fail at a high rate while working proactively to hide this system from pilots is beyond negligent. It's beyond incompetent. It's just malicious greed.

There is no hindsight argument in this case. This is an incredibly simple and easy to understand system, even for a layperson. The few people I know who have worked in real mechanical engineering systems are having meltdowns over how bad the design was.
