I'd say it's somewhere in between. It can't incompetence because there will absolutely be engineers and designers who knew of the risks inherent to moving the CG and CoL and the deeper concerns of replacing these risks with a software solution (MCAS) which can relieve a human pilot of control. There is no way any self-respecting engineer with enough design influence would have been ignorant of the potential risks with this design. It's probably not malice either because people generally aren't evil - especially those building planes which carry humans. In saying that tho, there was almost certainly a "trade off" decision which was made, and thoroughly justified which traded safety for something else: most likely project delivery schedule. Was this motivated by economic reasons? Who knows. But the trade-off decision which sacrificed safety (even if in largely unknown, distant terms) would have definitely been there and was certainly a conscious decision. IMHO.
