There was never any evidence that a software glitch caused sudden unintended acceleration in Toyotas. The problems were caused by defective floor mats and driver error.

The specific causes were determined to be non-software, but when they took a close look at the software, the software was atrociously bad.
I'm not sure Boeing's software, even if not at fault, will be entirely flawless.
The way this particular glitch plays out sounds suspiciously like software, or a software-like function of the MCAS unit.
