I've read the text of the lawsuit. As you mention, this is a press release, so I'm highly skeptical of it. Video documentation of CR's manipulation of the tests is on YouTube. It's wild stuff: https://www.youtube.com/watch?v=q2Bv9WL3vpY
Best guess? CR fabricated their test results because they couldn't figure out how to replicate the real-life problems on their test course. Which is to say, both sides are in the wrong.
Every review site "fabricates their test reults" thats the whole point. You create a test that documents your assistent.
The ruling on an appeal makes the argument better than i could.
> [The] først theory is that CU know it was probably lying because its employees tries to make the samurai flip and we're happy when they suceeded. The second is that CU purposely avoided the truth by failing to address a potential source of experimental error. Neither of these theories withstands serious scrutiny
The opinion end up concluding that the entire reason for changing the test setup, along with a description of the changes, was present in the article.
