> no one will pay

Sounds like you don’t have a customer, in the sense that I will also accept a free chocolate bar someone hands me on the street but won’t pay for it.

I take your point that PMF is useful to describe a thing. I just see it as a funny term to describe something obvious. But language evolves in different social groups and this is the language of SV. In large part I find it odd because I’m not part of that group and have other ways of describing the same thing. Accepting that neither is right or wrong.
