If people are clever enough, they will have no difficulty in finding out the information they want, or they will have it already.
You are assuming everyone has the same access to the internet as you. An inability to access the information/ known where to start does not make someone not "clever"!
If not, then they will make a possibly uninformed or instinctive decision, buy again, that's their prerogative. It would feel like undue influence to me if I tried to tell someone in Tha position what to think.
That is a difference between you and me. Rather than writing off the uninformed and undecided I would point them to easily accessible sources of information (with a yes bias, as I think that is correct). You will sneer and call them not clever and ill informed without actually offering any assistance.
At work, I would be a laughing stock and likely professionally negligent if I used Wings as a source!
That is entirely irrelevant.
