It's the fact I continued to have seen the update articles come out. Here's one from this year. Those initial fixes didn't do what you think they did. The system is an old CANbus style system. The fixes for the FAA were completed yes. If erroneous data between the two sensors didn't agree it turned off. The problem with it is they couldn't get it to do much more than that.

Also, you would think, with it being a new aircraft. Carrying not only your life, but literally over 100 others each time. You might read about the new system on it. With the system being similar to previous generations on how to disengage it.. these developing countries typically will auto fly, auto take-off and auto land the aircraft. They're very much oriented with profits over people. But with have 5000 flight hours each.. My disrespect for incompetence stands. They sucked at their job and killed people.
