Accd to the article, Hulu didn't know that the ID was the same between sites, and (imho) probably didn't care. The fact that it's the same was revealed by Wired, and users of KissMetrics appear to have not known. It sounds like KissMetrics didn't do much more than could be gained from a referrer in their linking between sites, though clearly more could be done if they wanted to be bad. (Yes, I understand the bad in placing an "unkillable" cookie even on folks who didn't want to be tracked; I'm referring to the specific concern you raised). There is no evidence in the article that Kissmetrics stitched these together in any way other than what is available in standard referrers. If you hand typed the info in, referrer is blank, and I don't think Kissmetrics imputed the referrer from their data. I don't use the tool, however; can actual customers let HN know if it actually does what Zed thinks it does? Because that would clearly be stepping some bounds if it did this even on "do not track" folks. And is the fact that it CAN do this is different from the fact that it CAN but isn't (well, if it actually isn't, see previous paragraph)? If they are, then let's yell. But if it's just possibility, then it's like yelling about Google seeing all my searches. The answer: Yes, they do. I can choose not to use Google, or I can benefit from their tech at the cost of sharing some info. Instead of believing that no one has any right to collect any data on my usage in a world where we leave digital tracks all over the place, lets instead work to minimize risk and maximize value for users. There is always data leakage, and that data can actually help folks if treated with respect and ethics. And yes, actually, Hulu could use that data to improve their product. But if you don't want to tracked, it's none of their business and they'll have to find another way. |
