The arbitrary requests for new types of user data are especially concerning. It's not hard to imagine what kinds of situations may arise from that.

Maybe I am just a far out anarcho-whatever, but surely it's not a completely radical idea to just use a browser and have a reasonable expectation that your activity isn't being collected and sent back to a central collection point to be analysed by "scientists" by default.

Also another important point. This type of data collection is neither necessary nor required for product improvement or bug fixing.
