>Even if it happens within a platform it's still a very concerning problem.
I don't necessarily disagree, but "Xcorp is presenting personal data that you've released publically in a misleading way" very different than "Xcorp is giving personal data that you assumed was private away to third parties". I think the second is a lot more serious than the first.
>If a company decided to put cameras in people's homes to improve "customer service" that business would be out of business the next day.
I'm not sure I agree, given the popularity of smart TVs and the recently announced Amazon Echo Look. I make no judgement of whether this is good or bad (I personally don't have any always-on recording devices), but I don't think its true.
>I understand that this is a result of people not wanting to pay for access to websites and online-services but, in my opinion, that's because they don't understand the ramifications.
See, and I disagree here. There are certain kinds of services that money cannot provide. Google Now recommends news articles to me, it can give me reminders about upcoming events from my emails and Google gives me some personalized search features (ie. if I type "frequent flyer number" into the default google search bar, my number appears, scraped from an email years ago). Those features have a utility that I couldn't get from an application that didn't track information about me. Potentially I could self host something with that level of utility, but it would take a research lab and millions of dollars to create.
On the other hand, reddit, which tracks comparatively little information about me, reliably recommends trending posts that are of zero interest to me.
