Exactly.

Formal methods do have their uses and software developers should be
aware of them as an option.
-- Aimed at the general audience
The current culture of intellectual dishonesty in the formal methods
community is switching off interest from potential users.
Justifying excessive claims by using weasel words to show how
wording can be interpreted to reflect reality is not the way to
convince people to try something new.
Researchers should ask themselves whether their paper would stand
scrutiny from the advertising standards authority.
Soap power manufacturers have their claims scrutinized and I think
we all agree that claims made about the use of formal methods should
also meet this minimum requirement.
