If your claiming your philosophical stance is setting passwords doesn’t provide security, by your own reasoning in your case that’s just a matter of practicality. There is no philosophical argument.
> More generally, I don't think that closed networks substantially improve security and I don't like the push to require them.
I mean that’s just your opinion, not a philosophical stance, and it happens to be a empirically demonstrably false one.
> I don't like technology that tries to enforce its own opinion about social norms.
This statement is so vague it’s practically useless. It can just be selectively applied against anything you don’t like. All technology is opinionated. From the layout of your keyboard to this site, everything is shaped by and shapes social norms. It would also be an opinionated technology if it decided not to ask you to set a password by default. You might as well have said I don’t like WiFi passwords because I don’t like WiFi passwords and it would’ve carried the exact same message.
