Probably not an attack. The plane had a history of issues leading up to the crash. I think the saying "never attribute to malice what is attributable to incompetence" applies here.
The point of the article is to exonerate the pilots and expose a broader issue of honesty and transparency from Boeing and regulators that is covering up a systematic defect in Boeing aircraft design. The shared electrical bus renders other redundancies ineffective. The fact that the RAT has recently deployed 37 times uncommanded means another electrical failure at takeoff is a matter of time.
When you ask "why" 5 five times, it's never an individual. That's a big part of safety culture. Otherwise people cover their rears and don't divulge information that would save lives.
Aside: Isn't it wild that due to a software bug, Boeing directs airlines to reboot their 787-8s every 51 days?
