They were telling investors the tests were actually running on machines though which is factually untrue and were lying in materials sent to investors about the testing done on devices and the validation of those tests. This is far more than just having a narrow slice demo and saying "this is a demo of what X will be like." What they were doing was directly lying about what the machines were doing and what they were capable of doing, beyond just lying to investors they pushed it out to the public using shoddy validation techniques which gave people incorrect test results.
