EU does not want privacy. They actually want to get rid of privacy every so often (adding backdoors in encrypted conversations). So far it has not worked out, but I’m afraid they will succeed at one point.
To follow along that line of thoughts, the requirements they are actually asking for proper DMA compliance would probably go right in that direction tbh.
I, for one, am happy Apple is taking a stance, and, as an European would really much like my government to stop asking ridiculous things that do not profit the consumer.
