Even if one were to agree with this description of Yudkowsky's behavior, it doesn't immediately follow that Yudkowsky is making the wrong decision. Again, "bad faith" is meant as a literal description, not a contentless attack—maybe there are some circumstances in which engaging some amount of bad faith is the right thing to do, given the constraints one faces. For example, when talking to people on Twitter with a very different ideological background from me, I sometimes anticipate that if my interlocutor knew what I was actually thinking, they wouldn't want to talk to me, so I take care to word my replies in a way that makes it look like I'm more ideologically aligned with them than I actually am. (For example, I [never say "assigned female/male at birth" in my own voice on my own platform](/2019/Sep/terminology-proposal-developmental-sex/), but I'll do it in an effort to speak my interlocutor's language.) I think of this as the _minimal_ amount of strategic bad faith needed to keep the conversation going, to get my interlocutor to evaluate my argument on its own merits, rather than rejecting it for coming from an ideological enemy. In cases such as these, I'm willing to defend my behavior as acceptable—there _is_ a sense in which I'm being deceptive by optimizing my language choice to make my interlocutor make bad guesses about my ideological alignment, but I'm comfortable with that amount and scope of deception because I don't think my interlocutor _should_ be paying attention to my personal alignment.
