offer an off switch to the data gathering
You mean like the "disable cookies" check box that has been in every browser for as long as I can remember?
Or a host of other user-oriented functionality, like client-side proxies which strip identifying details from headers, that are actually guaranteed to work - as opposed to some server side functionality that is trusted to do what the client requests in some bizarre header addition?
This has nothing to do with privacy or security, and everything to do with pandering to an ignorant public. You web designers - yes you - should know better.
