As an IT person for 30+ years, you should know better than to suggest that locking into Google as opposed to Apple isn't really a freedom. Of course you might be suggesting that you can buy phones from different vendors if you buy Android. I suppose that's true. As all the phones on the planet are basically the same design with minor variations right now, I just don't see the point. Cheap Android phones are damn near unusable and Android is completely unusable without a 5.5" or larger screen anymore and that's just WAY TOO BIG at least for me.
As far as I can tell on Android, you have as much choice as you want as long as you're willing to pay $600+ for your phone and you very carefully choose a screen between 5.5 and 5.7 inches and you make sure you get just the right.... just by the Google iPhone instead.
BTW, I do have a Samsung something or another for when I'm travelling. It's the T-Mobile version which is basically just short of a pre-installed virus. Thankfully, after 6 software update cycles, the base apps like Play, Phone, etc... almost don't crash anymore. I'm pretty sure T-Mobile is trying to convince you to come back and buy iPhones instead.
So back to the point. You have just as much lack of freedom on Google as you have on iPhone. The question is whether you are either willing to lie to yourself that the reason you don't use iPhone is because of a false sense of freedom or because you simply want freedom from Apple. I don't mind either way.
I actually probably am the opposite of you. I intentionally "spread the love". I use an iPhone with a Microsoft Office365 hosted e-mail account and make a real effort to properly exit Google apps when I'm not using them. I really don't care if Google tracks me everywhere, but I have personal anxiety at this time that one day, the Google board will replace the leadership of the company with someone focused on profits without a regard for morals... see HP, IBM, etc... At this time Google has more control over earth than nearly anyone else. They control more of the media stream than anyone else. They know where I am, what I look at, what I buy. They have my credit card numbers, my bank account numbers, my passwords, etc... they know what I'm looking at when I hold Mr. Happy in the palm of my hand.
One day when Google is either broken up by the government, is restructured, is simply taken over, etc... it would take one bad (malicious or accidental) decision from Google to literally destroy the entire world's economy or at least the lives of millions.
That said... using iPhone as it's the only alternative to Android gives me the sense that at least one tiny corner of my life isn't completely owned by a ticking time bomb.
