But to answer GP's question, AIUI, merely saying "Im going to murder this person?" does not make someone guilty of murder or attempted murder, or (perhaps surprisingly) even conspiracy to commit murder. Conspiracy usually requires an overt act, like buying a weapon, in addition to the statement of intent.
In addition killing is not always a crime.
Similarly, if Google was intentionally avoiding using anticompetitive language, it's reasonable to think that they felt they might be facing some anticompetitive behavior related action.
A lot of people are murdered in location A, we walk past location A frequently, let's not walk by location A anymore because the police are looking at us funny. Then they get pulled into the interrogation room and they use the fact that you stopped going by location A as evidence that you were involved in the murders (that kept happening even after you stopped walking by that location).
It's like if I tell you "It's not ok to murder people" or "We do not murder people" in an email and then a prosecutor uses that email to say I was conspiring to commit murder. If you have a predisposition to think I'm the murderous type, sure you can read it as me trying to obscure what I'm doing. Or you could look at it as me trying to communicate that we don't freaking murder people. Choosing to read it as conspiratorial, without other evidence, says a lot about you and not the group you are accusing.
At the end of the day I do think Google is too big for it's own good and perhaps they hit legal definitions of illegal monopolistic behavior. I do not thing this training is evidence of that fact and should, in fact, be evidence to the contrary.
If you're 100% confident that they're guilty, you should have no problem with providing better evidence than, "an employee said a nono word" or "Google told their employees not to say a nono word."
