Just imagine a European bank publishing a press release about how onerous the US credit card consumer protection laws are, or a Japanese car maker publicly whining about European car safety testing protocols delaying the market release of some of their models. Apple really is behaving in a very unusual way here.
And even though I don't like the implication of this (the law should not disadvantage anyone purely for being critical of it), I can't help but wonder how many fewer pages the DMA would be if Apple had engaged with its predecessors in good faith instead.
Both of these happen. European banks complain about American securities law. And all manner of car makers delay releasing vehicles in America and the EU.
Maybe China is easier to work with - perhaps their rules are made clearer?
