I think the point being made here is that 7500 would be used for unlawful interference like a hijacking or bomb threat. 7700 would be more appropriate for an interception.
The US has more resources at its disposal to finesse a forced landing. Less powerful countries have to resort to more barbaric means to achieve the same exact result.
Plane crew change squawk code to intercepted (7700) not 7500 which would indicate terrorist act.
What happened is clear even before crew and passengers start giving press interviews in Vilnius.
And please do not compare it to Bolivian case, then crew decided (to land) and was not put under duress by fighter plane.
