A recent criminal case in Canada was thrown out because the police decided to turn off their body cam mics while they had a conversation of what they were going to do during their arrest of the accused. The judge decided it was suppression of evidence by the police. (I agree with the decision).
A CEO choosing not to record certain conversations is, in my view, not that far from different. It's taking active action to ensure there's no record when it would have been easier to have the record: a clear sign that they don't want someone to know that was said.
