No commercial concern really wants you to be independent - ideally you should be locked in, preferably willingly. Apple are startlingly good at this and always have been. They have achieved this through a mixture of producing some pretty good products, top design skills and even better marketing.
Since Apple are not a monopoly - other phones, computers, etc are available, there is nothing forcing anyone to buy their kit so they can be as closed as they like from a regulatory point of view. Y'all may not like it but their shareholders and the majority of their customers (based on no research, just guessing) seem to. Oh, you can be as creative as you like, only they'd rather you did it using their products and selling through them.
