I'll answer your question with a question: how often do you see people complaining about needing setup processes vs the old way of just plug and play? There's no perfect answer that placates all sides. Things can certainly be better, but when those people win and you no longer need to have a setup process, then what?

While true that in $current_year it would be nice if things were more secure, the sad truth is that most people don't care.

I agree that yes most just want PnP and basically don’t care about security. But it seemed on the posts above that there was an engineering complexity, and a robot vaccum needs local WiFi, so there will be a setup flow. Whats preventing a password selection just be part of that?
