Apple limiting the way apps can be installed on iPhone can be both a security measure and a way to make money.
Personally I hope it stays this way. Forcing the phone to open up cannot feasibly be done without compromising security. Because you have to alter the operating system to make having an app not signed by Apple a valid app under some circumstances. Which means malicious actors now simply have to figure out how to get their third party app on your phone and toggle whatever switch on the phone allows third party apps.
Hopefully Apple keeps their core APIs absolutely locked down
Those things are not mutually exclusive.
