If your default browser is made by an advertising company, you should expect your data being used for ads and tracking by design (no matter what extensions or options you configure).
If you absolutely have to use Chrome, you can still choose Chromium as a less privacy-invasive alternative, but I think it won't solve the QUIC issue.
@raucao does QUIC respect proxies? I am still using privoxy in front of the browser
@saper I don't know enough about Chrome and Privoxy to answer that question. Sorry.
