>For some services I agree with your sentiment. But we don't have metrics so there's no way to know if this is a fair deal.
"fair" is practically a weasel word. It doesn't have a universal standard. It doesn't mean anything until you explain what you consider to be fair. I once read a book on negotiations that called it "the F-word" - it was warning you to be wary of people using the word against you.
Think of this as a transaction between two parties doing business together. When business A is making a deal with business B, then A is not entitled to know how much money B will make out of it. It's perfectly fine to ask, but B not answering is very much within the rules (and is the norm). It is your job to do your own research to figure out how valuable your information is to them.
I also often see an attitude of "They make $20/year from the information I give them. So I should have the option to pay them $20/year for not tracking me." No business deal works that way. Each party sets their own requirements. If you demand that they offer paid services to stop tracking you, they get to say "No - you're welcome to use someone else's service if they give you that kind of a deal"
Finally, the way negotiations work: The focus will not be on what they make from your money, but how much you are willing to pay for the services you receive. The majority of people I know will not pay $10/mo for their email service. So the fact that Google may make $30/year from your use of Gmail is irrelevant. This is your BATNA.
>Remember, they're showing us ads in addition to collecting volumes of information on us, so we're paying in two ways.
And in how many ways are they paying you in services? Far more, I imagine.
>Here in the US, we cried tyranny when our security agencies were collecting metadata to monitor threats. And then we gave everything we had to Facebook and Google and didn't bat an eye as they sold us to anyone who pays.
We probably hang out in different crowds, but while government monitoring did make the news, the percentage of people I personally know who cared about it was less than those I know who say "I'm using a service other than the one provided by Google because they're already tracking me in so many ways".
BTW, although I use some Google services, by and large I do not. I do not actively use Gmail. It was very difficult for me to get used to the idea of letting them get to me via Android. I don't use my account on Youtube. I don't have a Facebook account. I don't use Twitter. I pay for my own email and web services. I tend to have privacy extensions on my browser. I don't use Whatsapp. My life is not at all miserable.
