censorious appears to mean 'severely critical of others'. I expect they meant 'censoriously', with the full intent being that the embarrassment felt by the critical reactions of others when reading the instructions out loud will cause you to eliminate or fix obviously broken, complex or tedious processes that you had, until then, just quietly been putting up with.

I suspect they meant “scenario”.

Yeah that’s an autocomplete bug I didn’t catch until edits timed out. Thats “scenarios”.
