I look at it this way.This I think is why some people don't like fail forward. Your expectations of play are different.
I know this seems obvious, but for some reason we all want to re-litigate "my preference is different from your preference" over and over ad infinitum.
Saying "this technique works if you use Assumption A. This same technique fails if you Assumption B." is useful, objective information about game design.
Saying "I can't enjoy Assumption A, I can only play games with Assumption B." is a preference.
I couldn't care less whether or not you use or personally like Assumption A or B. I only care that when we discuss game design, people are aware that these assumptions exist and need to be part of the discussion.
Because 99% of the time on these forums when people say "This technique doesn't work", what they mean is "Using this technique violates an implicit understanding I have of how TTRPGs are supposed to work."
