Ridiculous example, seeing as how my bank is based in the U.S., it is therefore subject to U.S. laws whether I’m there or not. Apple isn’t based in the EU, and the DMA was written to apply to EU countries only, so by the way the DMA was written…those “protections” end at their boundaries. Guess you should air your grievances with the EU for not thinking about that.
A better example would be if an American citizen breaks the law in another country, would U.S. law protect them (assuming said action was legal in the U.S.)? Nope, it wouldn’t, because said citizen is subject to the laws of the country they’re in. And vice versa. Your home country’s laws and protections don’t follow you everywhere you go.
