A phone is a computer and a user should be able to configure it however they want. If that isn't for you then don't use it, but that doesn't make customization an inherent flaw because someone doesn't personally want to deal with it.
Customization isn't a flaw. Obsessing over customizability, to the point where you fail to notice glaring flaws in the user interface and the behavior of the device, is a flaw.
