Ambiguity is an aspect of language and how it's used, not what random people may or may not inferred from a statement. It's possible to be perfectly unambiguous, and still have some people get upset about things that you did not say. That's a big part of politics, in fact.

If you go with your definition of: something is ambiguous if someone, somewhere, might read things into the statement that aren't there, then basically no statement about anything people feel strongly about could ever be unambiguous. At some point you have to draw the line and say that if there's confusion it's the listeners fault, not the speakers (which is what labelling a statement as ambiguous means).

> You also mention people attacking straw men and a bunch of stuff about left-wing academics, that seems unrelated?

A straw man is when you attack a statement your opponent didn't actually make. If you claim a statement X is ambiguous because a statement Y is a fallacy but the speaker didn't say Y, then that's attacking a straw man.

The left-wing academics is related because for some strange reason they thought the best way to demonstrate utility was to try and show agreement between their technique and left wing "fact checkers", although the underlying point of their research didn't really need that.

If you'd like an opposing example, consider how statements by Bill Gates are routinely cast as evidence that he wants to depopulate the world. It happens because he says things like, "if we do a really good job of vaccines, maybe we can cut population growth by X%". Conspiracy-minded people take this statement out of context and then infer that Gates is stating a desire to kill people through vaccines i.e. direct causality, but he isn't as surrounding context makes clear, he's assuming a chain of indirect causality to do with better public health = longer life expectancy = less pressure to have lots of babies, and a defense of such an inference of direct causality by blaming Gates for being "ambiguous" would not be fair.
