Because it is not their job to mandate restrictions technology: it is their job to ensure the market is open.
It's their job to act in the best interest of the consumer. This policy saves the consumer money and reduces waste. Personally I find it great that I can ask an iPhone user for a charge, and likewise offer them a charge. I would say that this is acting in the interest of the consumer.
Yes they were - as you note, Apple were using USB-C when it was appropriate, and may well have moved all devices to USB-C under their own steam without legislation.
Then they could have changed the iPhone when they changed their other devices, however they did not. There is a direct financial incentive for them to not adopt USB-C on their phones.
Rubbish - a primary reason for retaining the Lightning connector was to support the massive installed base that had billions of Lightning compatible devices and cables. "Anti-Apple consumer" may be roughly comparable to "pro-general consumer", but this is not a given.
The large majority of the user base already have USB-C chargers and cables. E-waste is bad if it's needlessly having to be replaced. However in this case its unlikely you had to replace your charger since you already had a USB-C one. I don't see how this is different to them dropping Magsafe on Macs, Lightning on iPads, or removing the headphone jack on phones either, where they had no problem making peripherals useless.
As has been pointed out, manufacturers like walled gardens, because it maintains the user base, but in Apple world Lightning connectors were a minuscule part of the garden wall. This does appear to be in the EU's remit, though, as if you squint you can see this as assisting the consumer in moving between suppliers.
Walls like this are anti-consumer. Anything that the government can do to remove these walls is pro-consumer. You're right that it was a small part of this wall, but that does not negate the fact that it is still a part of this wall. With enough small steps, Apple may become a respectable company, but by this logic we should just give up. Perhaps next the EU will tell them to stop using serialised parts, promote right to repair, fine them harder for throttling older phones, challenge Apple's app store monopoly, and make them support RCS.
Yes, we could. It wouldn't have made any technical sense to mandate (for example) standardisation on coax ethernet (which at the time was as fast as could be envisioned) but the idiots in the EU could have mandated it. It would have made just as much sense as mandating a transient connector.
I could not disagree more on this point. Only a few years after the standardisation of thick/thin ethernet was twisted pair in development. There were clear negatives to this technology, such as the shared bus topology meaning one failure could bring down the network, the difficulty of troubleshooting such a network, poor speed scaling with multiple clients, high interference susceptibility, half-duplex communication or the installation difficulty due to the rigid cable. USB-C has no such downsides, and has already seen widespread adoption. Furthermore, during the peak growth of Moore's Law, it was easy to see that data requirements would grow.
Regardless of its undoubted benefits, USB-C should have been transient - not permanent - because technology moves on. I am surprised that you think that "requiring its use would no longer be a negative for innovation", as for example USB-C is already too thick for ultra-thin devices; no manufacturer is encouraged to invent a thinner connector because it would be illegal to use in the EU. This stifles the invention of thinner devices, through legislative stupidity.
I don't know why you are acting like we are stuck with USB-C until the ends of time. Every standard is transient. If we refused to standardise anything, nothing would have any regulation. In addition, the consumer benefits outweigh the hypothetical future constraints. The mess of proprietary connectors on devices outside of Apple and e-waste are current issues.
There are also devices that are 3.6mm thick utilising USB-C. I think it would be hard to get much thinner regardless of USB-C or not. We aren't forced to use USB-C forever either. It would be perfectly reasonable for a company to bring their case to the EU court and argue for an exemption or propose a new connector.
I would consider this as an example of kludgy workarounds because of the restriction - by a stupid law - from creating a custom connector that could do a job.
They created this port in 2021, before any restrictions. I prefer this connector over something completely different. I am able to use USB-C to charge and power the device, and if I wanted to use an external graphics unit from Asus, it's nice that it can simultaneously break out the USB-C into more USB ports and provide charging too.
The whole thing is almost certainly a storm in a teacup, though, as Apple will doubtless move to wholly wireless charging as soon as it becomes feasible, and stuff the damned USB-C connector!
I don't know why you have a personal grudge against USB-C. You are not unhappy with it on the iPad and iMacs, so why is it bad on an iPhone. Nothing stops a new thinner device using wireless charging, and a slimmer port for high speed data.
