Earlier quoted context omitted.
It was not an argument, but a statement. If one model (pay as you go) causes harm to the whole industry (people know believe hearing aids do not work) then why would the industry continue?
I'm suggesting the model to use should be decided individually by members of the industry, not imposed on the industry as a whole. If some orgs want to use pay-as-you-go that's fine. If others want to offer more comprehensive service, that's fine too. I'm arguing for allowing the interactions to take place, even if some choices made are suboptimal.
As far as I know (at least for Canada, circa 2015) there were no laws or regs stating how, what or when to charge for services. --other than some kind of return period.
