I get how these things generally work, I just think it's absurd, at least as described in the linked article.
The article says that "wilderness paramedics" can administer it, so it exists in the paramedic scope for the state, a "wilderness paramedic" just being a regular paramedic with a handful of hours of extra training. It's not like you had an EMT doing RSI or something else that is solidly outside the scope of their training and certification. Paramedics give emergency drugs and antivenom is an emergency drug. So I don't see it really as a scope of practice thing, at least not of the type that should put someone's licensure in jeopardy.
The medical control part doesn't make sense to me either. They tried to contact who they were (presumably) supposed to contact for orders, and with that person being unavailable, contacted who was (presumably) the next most reasonable physician to seek advice and authorization from. Many places have standing orders to do what normally requires OLMC in the event that you legitimately can't make contact with OLMC. If I were to speculate, I would guess that this is what got them - perhaps they didn't actually follow proper procedure for contacting OLMC and are being accused of "medical control shopping" for the orders they wanted? Maybe that's where the "more to the story" lies. Who knows.
Those issues aside, what they did was reasonable and medically appropriate and resulted in a positive outcome. It's difficult to believe that anyone really thinks the patient would have been better off had they not given the stuff.
This is why the heavily protocol-driven mindset needs to die in favor of a clinical decision making approach, and this is yet another example of EMS eating itself. In a true emergency out in the real world, things occasionally just need to be done whether they are explicitly authorized or not.
