Think back to when the App Store was first opened. How much backlash Apple got over the concept that it was a walled garden store, and the option to independently load external apps on your iPhone was blocked by the OS software (you could jailbreak and play the cat and mouse game until Apple plugged the software holes). Basically, that this was being set up in a very bad way and would leave a lot of room for Apple to control what you could or couldn't do or what content you could or couldn't see on your own devise.
Remember that time? Remember the countless number of people who said they should be able to put whatever Apps on their phone as they wanted. If they wanted to use the App Store, great, but they shouldn't be actively prevented from loading third party apps on a phone they purchased. Basically, like how things run currently on MacOS.
This is an example of when Apple not only distributes what someone can install on their phone, but also actively prevents you from having the choice to install software via 3rd party solutions. This is what the original backlash spoke of. Not to the specifics of the WHOEVER is deleted from the app store this week, but the mechanisms by which it is possible. You'll find this story all over the place over the past few years, whether it's Apple using their leverage to charge whatever fee they want on app developers (feel free to read about Spotify), to blocking perfectly valid apps because they may compete with what Apple software does (feel free to read about Valve), or because an app has sexual content (remember all of the non-relevant apps that were deleted in the wake of that particularly ******** company initiative?).
