When does the onus come on to the user to stop using something if they want privacy?
I don't like my personal data being shared, but I do accept that my data is being used by companies that I have a relationship with.
I fully expect Amazon track me across their site, and I don't really mind that, those kind of metrics are useful to companies to better optimise their products. (eg, I worked for a company that tripled it's sales in the early days of the web by simply re-arranging it's order page, but we did need user analytics to work this out).
The problem for me is when companies share it with 3rd parties that I don't have a relationship with, or use their dual nature of their product to track me when not using their product explicitly. (Advertising trackers for people like Google and Amazon come to mind here, I don't want amazon knowing that I look at a particular website simply because they sell advertising to that website).
i.e., I don't mind Apple tracking what pages I look at on the App Store app, but if they're tracking me looking at pages on the Amazon app, or vice versa, that would be a problem.
If I didn't want Apple (or Amazon, or Google) to know what I did with their services however, I simply wouldn't use them.
(or maybe it's just the older I get I realise my secret plans for world domination are less likely to come to fruition and there's less reason to hide them from the world anymore).
