I’m not sure it’s a DMA issue, but I assume it has something to do with not giving third party AIs access to the same data as Apple Intelligence.
After looking at the Windows Recall debacle, I sure as hell want the AI companies far away from my phone. (I'm pro AI, but let's just say that I give the sideeye to using AI from Google or Meta...).
I am an Apple customer for reasons, and one of those reasons is that I chose to trust Apple with my privacy, and to defend my privacy and security from companies and governments that would like to crack things open and let unscrupulous companies in.
You'll say that I can always only use the App Store, and that sounds great until Facebook (which thanks to its dominance and network effect, is a necessary evil) decides it's only going to work on mobile if you get it from the Meta Store, and just bypass the protections that Apple enforces (and refuses web browsers). It's pretty bad that the modern equivalent of the old wired phone network is an information-gathering company that tries to spy on you wherever you go, but here we are.
The worst of this is that while I would be all for some reforms at Apple (better app store fees, play nice with Netflix and Spotify, more app substitution choices), a pile of bureaucrats from far away is hellbent on just breaking everything.
I think the consumer ends up little more than a bargaining chip in this battle. The EU will win, consumers' privacy will be exploited.
I'm older, and I'm glad I got to live through several golden eras of computing, before consumerism, corporatism, bureaucrats and capitalist cult leaders ruin it all.
