Apple does plenty of bad things, and many are worse than this, but it doesn't mean it's not fair to point out this one is bad, too.
It all comes down to "the vendor can do things with your computer you can't do yourself" in the end.
It's not even that. A console vendor that locks down everything behind the TPM helps to not deal with cheaters is arguably fine. A console vendor that is also a game develop and caps the FPS of all games that aren't their own is abusing their monopoly position in one market to gain unfair advantage on a different market.
More broadly, and not based on antitrust grounds but on property rights grounds, I am opposed to every kind of DRM. First, it should be legal to circumvent any and all DRM/anti-copying measures. Second, it should be illegal to deprive the next owner of their property rights so that you can exert ownership control over a product past its sale.
If I buy a computer, do nothing but install a keylogging rootkit on it, and sell it on to someone else, I would rightly risk jail time. "The malware is part of the product" is not a valid excuse. DRM is also malware. It should be prosecuted as such, and if existing legislation is found wanting, more specific laws need to be written.
