Business Insider clearly states they are drawing from a Reuters investigation story.
They are factually reporting that everything is sourced from Reuters.
If you want to take issue with what you see as "poor reporting" then take issue with the source:
Tesla blamed drivers for failures of parts it long knew were defective
Wheels falling off cars at speed.
Suspensions collapsing on brand-new vehicles. Axles breaking under acceleration.
Tens of thousands of customers told Tesla about a host of part failures on low-mileage cars.
The automaker sought to blame drivers for vehicle ‘abuse,’ but Tesla documents show it had tracked the chronic ‘flaws’ and ‘failures’ for years.
It sounds as though there is more than "one guy" and that the claims made are backed by documents.
