    Google blocked domain fronting after activists made them more aware of it. AWS told Signal to stop domain fronting after they explained how they’re circumventing censorship with it on HN. Seems like people should stop telling hosts about domain fronting

        Not just being snarky btw. There is something to be said for plausible deniability vs mutual knowledge here.

        It is difficult to believe that they learned from activists. They were aware of that element of their design. It had simply not caused them trouble. When Russia blocked their whole networks because of it, AWS + Google clients needed it to stop. Thus, they acted.

        I think it is reasonable to assume that activism made more people in the company aware, increasing likelihood someone asks whether it is worth the risk.

        To be more specific, my point is that (1) having activists push the message and (2) showing off your censorship evasion on HN both force the respective companies into having to address the topic

        Sure, “domain fronting” as it has been named, is a bug in any HTTPS load-balancing/cdn infrastructure, and more aware means more attention. It’s just in this case I think it’s hundreds or thousands of clients screeching that got the response, not the post on HN.

        And among those clients, many probably pointed to the post and said “this is why Russia bans you”. And so the article explains it away, rather than having to say they caved to their customer’s needs/demands.
