More importantly, it's not uncommon when crossing Air Route Traffic Control Centers (ARTCC) regions (eg. from Washington Center, to NY Center) for controllers to instruct pilots to change Squawk codes. Same applies when crossing from one country's airspace to another.
One of these drones, without a bunch of extra avionics would be unable to change transponder codes in flight, and talk with controllers via relay, that would probably double the cost of the drone, or at least significantly increase it.
So even doing something creative, like spoofing the transponder Squawk code, from another aircraft, probably wouldn't help.
Also, with Mode-C, and Mode-S transponders, the later used with ADS-B, which feeds all the flight tracking websites, the transponder transmits altitude.
A SAM operator will figure out somewhat quickly if an airliner is supposed to be at 10,000ft and 250mph but isn't according to primary radar tracking, but much lower and slower, that it's spoofing it's transponder.
The transponder code, assigned by various ATC would identify that aircraft as a civilian airliner when it checks in, and on the screens of the SAM operators.
Also, the speed and altitude of the airliner, even approaching Grozny would not be the same as a drone. Airliners, even on approach, are somewhat faster, probably 200-250mph, or faster, and much higher in altitude, at least 5000ft, probably more like 10,000ft until close to the airport.
I used to repair EEG systems, and work as an EEG tech.
A surprising number of people, especially prior to the Affordable Care Act, would call expanding public healthcare "Socialism", even though many in Congress are veterans. The late Sen. John McCain (R-AZ), A Vietnam veteran A-4 pilot, and POW, cast the deciding vote against repealing the ACA. He earned his military healthcare, and then some.

That said, there is a fair amount of discretion on the Captain's part, and if the pilot was unable to land at Oakland for an unforeseen reason, such as an ILS malfunction at OAK, then declaring a fuel emergency sooner may be justified.
Knowing that fatigue may also be a factor, which could also result in a missed approach, and they are required to have sufficient fuel for several ILS approaches before diverting, without using their final reserves, could push them to declare a fuel emergency.
Typically, the Captain would say something along the lines of "I can only hold another 10 minutes, before declaring fuel emergency", prompting ATC to get them sequenced for approach promptly.
Ironically, my friend has programmed COBOL on DoD mainframes, and still does as a consultant, having interacted with them for decades. Back in the 1970s she had a surplus IBM minicomputer that her father brought home for business use, and learned COBOL on that, and used the computer for furthering her legal research.

From the linked Wikipedia page, which explains why the takeoff wasn't as wild as it first seemed.
Here's where it got interesting, my co-founder was friends with the founder of another much more established startup in a vaguely similar space. The leader of the incubator was under the impression we were focusing on a different idea (we considered as a secondary, later opportunity) and concerned about a conflict between the two startups. If we had listened to his suggestion, we probably could have come up with a successful product opportunity.
At the end of the day, It was my own stupid fault for not listening closer to what was said, and analyzing the option to pivot into a more successful path.
