I get the sentiment, but there's absolutely no basis for what you're saying. There's no anti-trust issue because Apple isn't colluding with a bunch of other manufacturers to make sure they also do this.
There's no FCC issue because this isn't about denial of service or the phone going outside the bounds of what a cell phone is allowed to do in terms of broadcast strength and frequency.
There's no FTC issue because no one is forced to buy an Apple phone and there's no end-user expectation of being able to replace the battery on an Apple phone (which customers know when they buy it). If the FTC were going to get involved in this in any way, they already would have come down on printer manufacturers like a ton of bricks long ago, since they've been running similar toner and inject cartridge scams for years and years. Unless the batteries are exploding or have an unreasonably short lifetime compared to similar products, the FTC doesn't give a shit about whether you can replace them.
I get that it feels super-unfair, but the fact is this is a case where you just have to rely on market forces. Apple will just get shittier and shittier in this kind of behavior as long as people keep buying the phones. I don't and won't buy any Apple products. The only one I have in my home is a work-provided MacBook because I have to do software development and testing on it.
So sure, "fuck Apple", but don't expect the government to step in and fix something because you can't get Joe's Computer Shop to do something that Apple explicitly said only it could do. And before you make an argument that right to repair laws should let you do this, bear in mind that the consequences of installing dodgy high-capacity lithium batteries in phones has been widely demonstrated. All Apple has to do is say that they can't trust random repair shops to have sourced safe, reliable batteries and therefore not disabling the phone would present a danger to their users.
