Putting aside other aspects of your bias, it's ironic that you insinuate that a "slander" happened, because the opposite effect occurred (as described by slide 9 in my second link). The US Transportation Secretary claimed that Toyota was exonerated, even though the report given by NASA did not support that claim.

The “slander” (not a legally accurate use of the term) referred to the media campaign, which was effective around 2010-12 and has lingering effects, as seen here.

You're trying to dismiss a series of technical reports on Toyota's software engineering defects - reports that directly acknowledge that it's impossible to prove causality beyond reasonable doubt because of the software engineering defects - on the basis of their similarity to an unrelated report from 1989, and because you "smell a rat".
