I get why that would be someone's reaction. Unfortunately there's no way for me to explain what concerns me about the way things are going that doesn't make me sound like a prat :(
As outlandish as my comment may come off, all the pieces (maybe aside from Google leaking data) leading to such a future are conventional takes. As far as big companies leaking data, it's not that it happens every day, so much as it is the cumulative nature of leaks: each leak adds to the pile.
And if entrusting everything about your life to one company ever does backfire, you still won't get to call this out, because then it will be 'blaming the victims' ;)
I don't know the likelihood of this all going dystopian, but I did realise a while back that it isn't hard to pick a not-google option early when a thing is new. Rather than attempting to go cold-turkey you can just stop growing more locked in. After a few years you notice you're not stuck any more.
