I read the EU's DMA documents (and their responses to Apple) and what stuck out was that every time Apple brought up "privacy concerns" for any interoperability proposal, the EU response was basically: "that's invalid, protecting privacy is up to the law, not Apple".

Apple has their own greedy reasons for locking down their platforms, but the EU hasn't curbstomped Facebook and never will. So there's no question the median users's privacy will be worse, because apps will get deep OS access gated by permission prompts that they'll click through without reading (due to permission fatigue). The EU is captured by corporate interests, you're naive if you think "Apple loses we win". It'll be "Apple loses, other big corps win" as always.

Giving Meta/others access to most people's notifications (revealing everything about you), Wi-Fi networks (locations), iPhone Mirroring (unlocking and browsing an iPhone remotely), Continuity Camera (turning on your camera remotely), App Intents (basically making their apps an OS-within-the-OS). That's all stuff Meta has already requested from Apple under the DMA's interoperability requests procedure. Stuff Apple only does on-device, others will be able to grab and send to the cloud with little transparency to most people who don't understand this stuff.

> the EU hasn't curbstomped Facebook and never will

The EU fined Meta 200 millions euros for failure to respect the DMA regarding their data collection policy. That's on top of the 1.2 billion euros fine Meta received in May for failure to respect GDPR.

That certainly looks like curbstomping to me.
