      Absolutely not, this is just about choosing safe defaults. Nobody is suggesting you shouldn't be allowed to choose who is trustworthy. If you're lucky enough to only ever use trustworthy networks, great! Many people are not that lucky, and we should help them, right?

      As long as you define yourself as trustworthy, this is fine advice. Or in the words of a wise former coworker of yours: “I trust me; why shouldn’t everyone else trust me too?”

      Do you agree that the customers of the ISPs in the article you posted yesterday are getting a pretty bad deal? I understand some of those ISPs are probably PowerDNS customers, and you might not want to criticise them, but just in general? https://twitter.com/PowerDNS_Bert/status/1181212034878361601 …

      I personally think that this deal that Mozilla and Cloudflare agreed to sounds like a better default. However, users should be able to use their ISP if they prefer their policy - no argument there. https://developers.cloudflare.com/1.1.1.1/commitment-to-privacy/privacy-policy/firefox/ …

      I know, you always say the same thing - only PowerDNS™ customers can be trusted, everyone else has malicious motives they're not revealing. I think this is a weak and transparent argument, and you're going to look as silly as the people who argued against HTTPS 10 years ago 🤣

      If Google cares so much about encryption maybe it's a good idea to remove the royally buggy SSL/TLS keylogging functionality from Chrome. But that's just me

      I'm not aware of any bugs, if you file a report someone will take a look. The only thing I can think of you might be talking about is the SSLKEYLOGFILE thing, but that is not a bug.

      Yes exactly that feature which should not be in a regular consumer browser to begin with but I'm not talking about the feature itself but the fact it can send all your keys to a remote host instead of a file without any notice to the user what so ever

      No I did not I made a fully functional PoC doing exactly that, and this bug was filed almost 4 years ago and dismissed with "it's not a problem since you could do the same thing with malicious software via LD_PRELOAD" 🙄🤷‍♀️

          I mean SSLKEYLOGFILE is using unsanitized/unverified content from a environment variable feeding it directly into fopen(), you don't see any problem with that?

          Yes, not a problem, but thank you for reporting it, better safe than sorry! Hey, malicious software could just patch that feature back in if we remove it! 😄

          So the fact that something is also possible using malicious software makes it ok to provide the same thing by default?
