Nice that something more than strongly worded letters was done.
You mean the European hypocrisy when they call out "state piracy"? https://en.wikipedia.org/wiki/Evo_Morales_grounding_incident
2) Refusing to allow use of airspace is different from hijacking plane and abducting people. If someone is using "state piracy" only for the second one it is entirely defensible.
EDIT:
3) at least in this case I can say that my country (Poland) was not complicit, though probably mostly because they were not asked by USA to do so.
4) Plane was not forced to land, but landed due to technical malfunction
> pilots requested emergency landing due to issues with fuel level indicators and thus inability to confirm sufficient amount of fuel to continue flight
Though problem was triggered by France, Italy, Spain and Portugal refused to allow transit.
