"how many of those shapes are rectangles?" "sounds like zero unless they are squares"

Adding "unless" to a statement makes it vacuous if the latter clause is weaker than the first clause. I find it hard to believe that a company willing to violate licenses would have scruples about lying about it.

Not vacuous, but tautological. Which is different, because tautologies can actually be quite directly informative. Whereas vacuous truths tend to be oblique.

Also, “Microsoft is lying” is not a logically stronger statement, because they might be lying about something other than whether they distilled or trained on AI output.

I think that's the point. "How do I say they're lying without outright saying they're lying?"

It's a common rhetorical trick.

Or the speaker is just not in the mood to argue with someone whose response will be, "you trust anything Microsoft say?"
