You're being a conspiracy theorist. You can in fact replace the battery with a non-Apple battery without issue. The things that break when you replace them without a properly signed version are in fact related to the security of the device. It's not a "guise". I don't want someone with physical access to my phone to be able to access anything on the phone. If I can do this, so can anyone else.

No you can't. The apple batteries have a chip in them with a code that tells the phone they're authentic - only authentic apple components are allowed.
Its not a conspiracy theory. Apple is just a piece of shit company.
If you think being a piece of shit has to be a conspiracy, you're just naive.
