Always this sad argument that X is a private company and they can do what they like.
Companies are not acts of God or nature. They are a private company operating on a society that allows it to exist because it is believed to be the for the public good. The public has very much the right to question it's practices, and if they are anti consumer, monopolistic, or a list of other things, to correct them. Shareholders be damned.
So what's your argument then? Companies can't release a product unless each and every feature works with their competitors products? By that logic most of the software and hardware you use today simply would not exist.
Like a lot of parts of the (especially earlier revisions of) Bluetooth spec the battery status took a slapdash approach to defining things. Look at anyone who's used Bluetooth on Windows to see what a nightmare interoperability still is. So Apple released ear buds that implement poorly defined parts of the spec but otherwise work with third party bluetooth devices, and that's bad?
Yikes.
Meanwhile, the Bluetooth SIG released an update at the end of 2022 that actually starts to require some sort of standardization. You know who's name was on that little update? Big bad awful anticompetitive Apple.
