I think it's fair to call out the parent comment for things that are not exactly caused by Boeing (eg: the engine failure), but I also think it's important to look at the why.
In the case you're referring too, the focus was on poor training and failure to follow up on earlier incidents. It's not the same as designing a system based around a single sensor that is known to fail or forgetting to bolt a door.

Right, they designed the their system with two sensors, and if they disagree, the system gives misleading indications to the pilots! That’s so much better!
My understanding is that the Airbus equivalent (they don't really have the same thing) uses 3 pitot tubes/angle of attack sensors, not 2. More importantly, Airbus pilots know about the system, while Boeing only told airliners about MCAS after the Lion Air crash.
I'm not a pilot and I don't know that much about planes, but I've read/watched enough about crashes to know that these sensors fail way too often. To rely on only one already sounds like a bad idea, but it's irresponsible not to tell pilots and train them on how to deal with the new "feature".
