>To prevent ad fraud either you need to increase the fingerprintablity of users on the web, violating people's privacy, or implemented a form of remote attestation, which protects people's privacy.

>If EFF cares no much about privacy on the web they should be in favor of this proposal.

Privacy on the web by implementing remote attestation across the web will inevitably in practice reduce digital rights and user control/freedom. The EFF also cares a lot about this, so it makes sense that they would be against the proposal. Both of these goals could be achieved by websites providing the same behavior regardless of the client browser/software that is requesting pages. The reason we have to lie is because user-hostile businesses/sites don't want to adhere to this (advertising, DRM). (ignoring useful things like providing a mobile version of a site)

To note, fingerprinting is always going to be technically possible (especially given the larger and larger feature scope that businesses have wanted to impose upon the web since its inception), WEI is just an attempt to stop ad-driven sites from trying to do it.
