You're welcome to use whatever hardware and software you like, just like you're welcome to eat what you like or wear what you like.
What's rather less welcome is when you insist on throwing out claims that have no basis in reality. You appear to know absolutely nothing about Apple and the Apple eco-system, and under such circumstances it's rather more polite to keep quiet and either ignore the conversation or try to learn from it.
Apple has no lock-in regarding music. Music downloaded from the Apple store is in standard AAC format that can be read by any decent modern chip and can be transcoded to MP3 if you absolutely insist. Music from the Apple store was encrypted in the first few years at the demand of the music licensees, and that encryption was removed at the behest of Apple.
Your anger at Apple, meanwhile, is blinding you to the reality of modern computing. You're looking at the world through Windows95 eyes, when the interesting things that are happening (across ALL the tier one vendors) are things like the replacement of a single personal computer with a personal compute eco-system, the replacement of the threat models (and security solutions) of 1970s UNIX with the very different threat models (and solutions) appropriate to this personal compute eco-system, and the very new and currently completely wide-open space of ambient computing (which requires a whole new set of security solutions, along with a whole new set of user interface paradigms).
Beyond that you seem to have some sort of personal grudge against people who prioritize buying certain devices rather than others. Let me just say that this is foolish way to live your life. Other people differ from you, and if you insist on getting lathered up because THEY'RE WASTING THEIR MONEY BUYING A NICE IPHONE rather than doing what you would do and spending the same amount of money or more on, I don't know, a trip to South America, a 4K TV, your annual alcohol (or restaurant or theater) bill or a whole bunch of things I could not care less about, then you're going to find yourself ever more isolated and alone.
Looking at people you know nothing about and telling them "your lives suck and you're stupid in the choices you make" is a fine activity for people wearing bathrobes standing on street corners, but, IMHO, it's not really appropriate for this forum. How about we all agree to stick to commenting on TECHNICAL details, and correcting each others facts, and leaving the value judgements for reddit or 4chan?
