I strongly object to the inclusion of any definition of tracking in the TPE. It is unnecessary to defining the technical mechanism for transmitting a user's DNT preference. It's inclusion outside of a broader document that fully defines and describes the meaning of a DNT signal will be highly detrimental to the specification, because it would create considerable ambiguity and therefore risk for potential implementers. However, because it seems likely the chairs will elect to include a definition of tracking in the TPE despite strong objections to doing so, I will also state the following objections to this particular definition: 1. While I support the focus on context, I object to the finalization and inclusion of a definition of tracking that relies on vague, undefined terms, such as context or sharing. 2. Additionally, I specifically object to the portion of this definition that applies to "data derived" from users' activity. This is over-broad in that it could include data and data uses that should not reasonably fall within the definition of tracking, including, for example, aggregate data, or other data that is not tracking data.
