I've worked at a startup in the past where the design team requested we put artificial delays / fake progress bars in. I told the design team that 1) Its just bad design / hostile to our users, and 2) that I'd quit before I'd build it for them.
It's a hill I'd be happy to die on. I feel like 6/10 engineers wouldn't care to have that fight, let alone risk their job over it. I'm lucky to be in a position that I am even able to. So many are not. Yet another example for the banality of evil.
