But can the EU do anything about it? It just goes to show the challenges of trying to legislate a particular course of action. You can list out what you want them to do, but you cannot tell them what not to do.
Exactly. To your point, if the EU had said "you can't do X" they would have a spec that did not allow for any faster speeds, since they would have fixed all the details into the directive. Charging speeds would be limited to PD, data to whatever USB speed they decided, etc. People would be screaming the EU prevented the from using Thunderbolt or any new, faster spec the standards committee approved. Until the directive was amended, the EU would be behind the rest of the world.
Well ofc they can and if Apple tries something like this they probably will.
And you certainly can tell them what not to do. You do it through legislation. You make the initial law and then subsequently close any loopholes and clarify the original law, again, through legislation
There is no loophole. The EU set a minimum charging requirement and allowed manufactures to include any additional features they wanted as long as the minimum requirements are met. It would not surprise me to see other manufacturers doing similar things to differentiate their products from Apple and other competitors.
And the initial rumour seems suspect, as I find it hard to believe Apple would be hacking the USB spec to not allow the use of valid USB-C cables.
Nothing would prevent you fro using a generic USB-C cable for charging; much as you can today. MiFI would only come into play beyond the EU required performance, assuming Apple decides to go that route.
Only Apple would deliberately slow the standard speeds of a port standard down, to force you to upgrade for more profit on their bottom line. Always upselling is Apple.
There is no "slowing down." They may simply decide not to use a faster available one, for whatever reasons they choose. They still would meet the port's standard.
Apple can chose whichever USB spec to follow in terms of data transfer speeds, or even develop their on data transfer protocol and still be USB compliant.
OnePlus has been doing funky things with USB-C for quite some time now. Except they do so to enable extra features and promote sales of their own line of accessories that offer things like super fast charging... whereas this seems more like a punishment to users to force them to buy Apple's overpriced accessories that offer basic functionality like wired charging.
The rumor suggests Apple may be doing the same:
The iPhone 15 and iPhone 15 Pro's USB-C port and accompanying charging cables will feature a Lightning-like authenticator chip, potentially limiting their functionality with Apple-unapproved accessories, a rumor...
Apple could very well replicate today's scenario where unapproved accessories give a warning, but still work; while approved cables are capable of faster data and or charging speeds beyond the mandated minimums.
Of course, all of this is speculation based on an unsubstantiated rumor on a random site.
