Not naive.
The truth is not liked by all
I can't help that
It depends which version of the truth is preferred. I come to this forum precisely
because of the opinions shared about the window cleaning industry. You appear to state that anyone who does not like a particular product should take it up with the business direct and not share that here - I simply don't agree that that is constructive either for the window cleaner or for the seller/manufacturer.
I believe that I, along with other window cleaners, can differentiate from posts which are openly critical for the sake of it, from those which are airing real concerns for a poorly designed/constructed product. I don't think that it is useful to hide all criticism under the guise of the risk that it may 'defame' a reputation; a reputation can only be enhanced where the concerns are handled, responded to and dealt with in a calm and professional manner. Those 'critical' opinions offer an opportunity where both the manufacturer and the window cleaning community can all benefit.
Your comparison of customers with issues is also instructive - if a customer was delighted with your service would you prefer them to not tell anyone if asked? They should only tell you when they love your service?
The benefit of this forum is that we are able to give honest, albeit subjective, opinions. To attempt to limit those opinions by the removal of posts by moderators is naive.
