Trillium, Let's be clear about a few things. The only data that checkusers get is a subset of the data that the WMF webservers (and all other webservers throughout the Internet) collect on all visitors. This is data that is voluntarily disclosed by readers (although they may not all be aware of it). The checkusers get substantially less information than is actually available, and only on those users who *edit* and not those who simply view. That means that while you are correct, the Wikimedia community at large certainly includes all readers, only editors are stakeholders in the exposure of certain data to checkusers.
