> Could you find one economist that would say that an unpriced externality is not a subsidy?

All of them?

>This isn't a tortured analogy, it isn't an unconventional use of the term, these things are economically equivalent.

No they are not. This isn't the equivalent of a tax break that other companies are being taxed for. It's a think for which no taxes exist for anyone. No industries are being taxed for these externalities.

It doesn't fit any of the dictionary definitions: https://www.merriam-webster.com/dictionary/subsidy

>Most people don't know the word "externality," so using a less precise term that they do know is not in any way deceptive.

It's not a less precise term. It's the wrong term. Might as well call it a bailout if you're going for political outrage.
