This is absolutely not true. This is what they ACT like, but this is not their true motivation. These companies want all control to be theirs, and they want to be free to do what they want with users and their data, and they want to spend as little time, money and effort as possible while doing it. They know they can't state this honestly, so they dress it up in excuses, rationalisations and outright lies.
They KNOW they don't know better than its users. But they don't want to let users decide, because users would make decisions that go against their own profits, so they remove the choice and lie about why.
