Apple always had this model. From the start... So people who bought into the ecosystem did it fully able to understand the system. This isn’t some creepy unexpected recent change... if someone doesn’t like this system then they should (past/present/future) put on their person pants and buy a different phone. I use Linux and Mac specifically because I didn’t like the way Microsoft was doing things. I didn’t start a movement to somehow legislate handcuffs to force Microsoft to address my whims, I just voted with my time, attention, and wallet.
And yes, do think others are free to chose too and should own their choices. If Apple stops providing me the best avenue to the things I want then I will switch. But right now I want ease of use, and the most confidence that things will just work and work well. I want this in the hardware, the OS, and the apps... and I think Apple provides that best. If my needs change, or their ability to meet those needs changes, then I will move to the place that does it best then...
Regarding the “don’t HAVE to use it” argument... I humbly suggest it’s irrelevant. They don’t have a monopoly so we don’t have a public overriding interest in messing with them. I’m saying that I don’t give a hoot about them having a side store: I want to quickly and confidently find the best apps to fill the needs I have. I will pay for the ability to do it as time has value. After that need is met, not much else has value and so I’m (personally) happy in the store. I’ll also suggest that Apple’s success says that a healthy number of people agree. This leads me to think that all the people who want to better sell crap to me that I don’t want are showing a bit of a case of “sour grapes”.
