This can end in several ways, users and third-party repairers will reverse-engineer phones encryption notwithstanding—simply remove the 'offending' chips and replace tbem with open tech.

To say it's unlawful is moot. Apple may have jurisdiction in the US but not across the globe, there are plenty of places I can think of to send an iPhone to have it fixed the way I want (and I'd do so the moment that market is established). There's no way Apple can police what people do with their hardware once it's in their hands, it's fanciful to think otherwise.

Open hardware is on the move, eventually considerably cheaper open products will become popular just on price alone. Competition will then be fierce, Apple will have to change its policies if changes to laws don't beat them to it. Remember also the US isn't the whole world, so those changes are likely to be enacted first outside the US. If Apple wants to sell there then it'll have to comply with those laws just as it did with USB-C in Europe.

Also keep in mind Apple, Google, Microsoft etc. have become the richest and fastest growing corporations in human history—they even beat out the previous contenders the Dutch and British East India Companies of the 17th and 18th Centuries.

These corporations became so rich so quickly because of a confluence of circumstances—the new tech paradigm of the personal computer, the wow factor that took the world by storm and a compete lack of regulations worldwide. Without regulations to keep these corporations in check they simply ran amuck.

That's now over. Yes, it will be some while before they're brought to heel but they'll never get such a straight run again.

Apple is on top now but let's see where it'll be in 20 years.
