A business needs to make and maximise profits, so what's wrong with charging for a service? How is $19 "greedy"? And why do you think they deserve such harsh punishment? They've done nothing wrong.
They don't have a monopoly on the market, it's just a website with a service who charge for it.
These gripes are fine with mandatory things like petrol/gas, mortgage rates, etc, but it's not an issue for an online service which can only be used if you have tens/hundreds of thousands of dollars to spend anyway. So then $19 is acceptable. If they removed the $19 fee, would you suddenly use the service?
They are not being disrespectful to anyone. All businesses have different protocols, and individual needs dictate different specific approaches to manage the business. Maybe they get 100 or more spam and lowball offers every week. I wouldn't want to deal with all that when I only have 5 and 6 figure premium names to sell, would you?
Also, "window shopping"? You think they should spend time or money trying to accommodate people who are just window shopping? Bearing in mind in context of the discussion, "Window shopping" is sending lowball offers (as the $19 is all about not being able to send offers, nothing else).
Are you against members only clubs? Because you should be entitled to enter and use the facilities?
"Superiority complex", "need to feel above someone"? Why, how, have you turned a business' basic payment charge for a service into something entirely emotional? You said yourself you run a business, do you provide your services for free?
