As far as I can tell this basically means that all apps must be approved by Apple to follow their “platform policies for security and privacy” even if publishing on a third party app store. They will also disable updating apps from third party app stores if you stay outside the EU for too long (even if you are a citizen of an EU country, with an Apple account set to the EU region).
The idea that preventing app updates is in line with their claims of protecting security is utterly absurd. “Never attibute to malice what can be explained with stupidity,” but Apple isn’t stupid.
1.8B was the fine they got for anticompetitive behaviour with regards to Apple Music, which is not an insignificant amount for that business unit.
The fines for DMA-violations go up to 10% of global revenue for first-time violations and 20% of global revenue for repeat violations. I would love to see Apple continue fucking around and letting Apple find out in the form of a fine of that magnitude. It would be so damn sweet.
For the first violation, they chose to go for 0.5% instead of the 10%. I’m not holding my breath.
