Earlier this year, a youtuber speculated on the cause of a (small aircraft) crash and was threatened with a lawsuit by the family of the pilot- he had to issue a full retraction.
Given how early the investigation is and the magnitude of this crash, I wonder how open the author is to being sued by Boeing? How is this any different than the youtuber lawsuit? Any lawyers want to weigh in?
I was going to say, this is just a list of accidents and ADs with no actual analysis or even an attempt to explain specifically what the through-line is. I'm no Boeing fan, and there may very well be systemic issues that need to be addressed, but this article hasn't succeeded in identifying them.
I read it more as a timeline of Boeing failures and the type of reputation Boeing now (rightfully) has. There is little speculation about what actually happened to the Air India 787.
"Boeing 787 to lose all AC electrical power due to generator control units simultaneously entering failsafe mode."
The aircraft computer uptime was 248 days. It needed to be rebooted. Yes, it that's stupid of a software bug.
A 2016 Airworthiness Directive requires "repetitive cycling of the airplane's electrical power system."
a Model 787 airplane that has been powered continuously for 248 days can lose all alternating current (AC) electrical power due to the generator control units (GCUs) simultaneously going into failsafe mode. This condition is caused by a software counter internal to the GCUs that will overflow after 248 days of continuous power. We are issuing this AD to prevent loss of all AC electrical power, which could result in loss of control of the airplane.

Another pilot agrees: this was software

Was this the uptime of the Air India plane? Or it's just speculation?
