That’s decidedly not what owning your clickstream data means. The argument is that users should be able to decide to give away their data, whether they can later access that data is irrelevant. Access to the collected clickstream data is simply not part of the agreement and as long as users are not coerced or tricked into agreeing that’ certainly unproblematic. (I can similarly agree to give away my photo collection without getting any right to access it ever again. That doesn’t mean that I don’t own my photo collection.)
You just said you can give away your photos by agreeing to not have any access rights to it and still own those same photos. It seems like you are using a different definition of "ownership" or maybe "click stream" than I am so this argument is pointless unless you define exactly what you mean by those words. By "click stream" I mean the aggregate history of clicks along with contextual information related to those clicks as one coherent, single entity and not individual clicks looked at one by one each of which was owned by the person that generated the click and who transfered ownership of that single click to somebody else. If you meant giving away a copy of your collection then that's a little different but that's not what's happening with user generated click streams. The only click stream copy is the one at google, microsoft headquarters and you have no access to it so you don't technically own it.
No. You can give something you own away. You obviously don’t own it anymore after you gave it away. Being able to give what you own away is part of ownership. (You can’t give something away you don’t own.)
Since you can still make a local copy of your clickstream data (every browser has some sort of history function) you don’t even really give it away, you keep it and hand over a copy (maybe not technically but it is still the exact same data) to Bing.
Here is an analogy: Imagine a scale which, after you agreed to it, automatically sends your weight to the manufacturer every time you use it. The manufacturer made it clear when you agreed that you will not be able to access your weight history. While slightly creepy, I don’t see any ethical or legal problems with that. You own the weight displayed on the scale, you can therefore also agree to send this weight to whomever you want, even if they don’t let you access your weight history. You are also free to make your own local copy of your weight history (for example by writing you weight on a piece of paper every time you use the scale).
