Can you provide evidence and references that Apple has not paid taxes that were actually owed the US government?
Here's the official press release from the European Commission claiming Apple owes 13bn Euros in taxes that had been saved with illegal state aid they had negotiated.

They will do this sort of thing almost everywhere.
And in many respects it's hard to blame them. Probably most of us here would behave with similar greed if in a position to do so, especially as the benefits are largely felt by the top execs. So Cook can virtue signal on twitter while *innocent face* in the background lawyers exploit every possibility to twist rules to save taxes. All men are capable of greed and hypocrisy; I blame the governments for not taking the gloves off when it comes to companies like Apple.
