Mozilla is pretending to be a health store. But we are starting to see that they are also peddling drugs. Not Google drugs - drugs with security and drugs with delivery system and drugs that we are pretty sure how they work - but some other drugs, from shady producers using shady means.
Mr. Robot.
Google tells me - "Dude, for providing me your information you get gooodieeeees!"
Mozilla tells me - "We respect your privacy. "
In a micro-font : "except when we do things that you should not be concerned about"
The really annoying ads which auto-play videos, block content, etc., tend to be served by companies who aren't taking the long view --- which is why Chrome is going to be adding adblocking for those ads that are ultra-annyoing early next year.
There's a pretty big difference between "using your information for marketing", and "marketing your information to advertisers". The second implies that your private information is getting divulged for a price, and that's simply not true.
If I narrowly target an ad and then I know you saw it, I now know all those things about you.
So, yes, they do not literally sell your information, there is one level of indirection there. And the amount of information that data brokers get their hands on tells me that it is very likely people are exporting this information regularly.
and what other uses?
You do? Okay, I don't. Please, show me exactly how Google uses data they collect from their users. Every usage. Not just a few. And no "but they say they can use it for whatever they want!" - then we can talk about transparency.
