Well, technically the failures of MCAS should be unproblematic, as the stabilizer runaway protocol is well trained for any 737 pilot and would cope with a MCAS misfunction. The problem is: in the two crashes the pilots either completely failed to follow the protocol (Lion Air) or to late and failed to recover (Ethiopian Airlines).
... without triggering re-evaluation of the seriousness/consequences of failure. That meant that failures of MCAS were considered unproblematic, which meant that lower levels of redundancy were deemed acceptable.
Quite a process/management failure.
