"My whole argument is that in singaround/session environments each performer has the right to perform in whatever way they like without people like you telling them this isn't right or that's not acceptable."

But, Bignige, I am expressing an opinion - not dictating to anyone. Whether crib sheet users pay me any heed is down to their individual consciences.

In addition, I think that the distinction that you and others make between a paid performance and a singaround situation is a false one. Surely, every singer should give of his/her best whatever the situation. After all, does a professional like Martin Carthy (or GSS for that matter) deliberately give a poorer performance when singing to members of his family?

Traditional singers, like Harry Cox, Sam Larner, Caroline Hughes etc., etc., etc. would often sing to their mates in the local pub or to their families. Did they deliberately lower their standards if they weren't being paid, I wonder?
