Google could have avoided all of this blowback over WEI by simply calling it "HTTPS+ Everywhere" and pretending it helped user privacy only.
I'll grant there are a few more TLS CA options than possible WEI attestation options (if they really are to come from the OS vendors like the spec suggests). But not that many more and any legal pressure applicable to one is applicable to all. Both Google WEI and Google QUIC HTTP/3 are terrible and both need opposition or at least mitigation.
And before anyone goes there, no, setting up your own root CA is not an option. Unless you get can Google/Apple/Mozilla/etc to include your root CA in their browser trust stores it doesn't help a random person visit your website at all.
So long as there's a way to bypass verification or configure the trust store I'm okay with it. Is there official policy stating that this won't be possible or is this prediction?
As I understand it the primary reason for this push is that non-technical users too often skip security warnings, but I'm of the position there MUST at least be a way to bypass verification no matter what (through keyboard combos or a configurable trust store).
