Yeah, the Chrome store policies (https://developer.chrome.com/webstore/program_policies https://developer.chrome.com/webstore/program_policies) do include a note that almost certainly kills this: "We don't allow content that harms or interferes with the operation of the networks, servers, or other infrastructure of Google or any third-parties." I think Chrome Extension distribution outside the Chrome store is more or less blocked, so that's that. A FireFox version would probably be fine though, assuming this doesn't actually break any laws (IANAL, but I'd be surprised). Alternatively, you could build exactly the same thing as a standalone program on your computer that does this as a local proxy, or even by building something like pi-hole (https://pi-hole.net/ https://pi-hole.net/), to automatically break analytics data from everybody on your network.
