My point was that if the people who control X have interest that X be Y, then X will become Y over time, even if it's not Y currently.
Sure maybe the people with Google phone X but over time we should expect that Google will find a way to Y, because that's where its interests lie. (And actually, we've seen it do exactly this many times. Chrome being the most obvious example).
Here's yet another example. If voters can be bought by promising them money, then we should expect that politicians will start promising money to voters in order to be elected.
Etc etc, do you see the pattern? My point wasn't actually about privacy, or Google, or Monero.
