I dont to start a "war" with you, just leave my point of view...
You made your point of view. And none of the moderators deleted your post because yes, you are entitled to your point of view and to make it known.
Do you expect that I wouldn't respond with my point of view? Or are you expecting that only you are entitled to your point of view?
My response was meant to point out that if you read all 15,500+ of my replies you'd notice that I don't
only (as you put it) sell my services.
If your main core of business is comercial services supporting DA the money you pay to that developer and the exim config you write (the time you spend on that aka money) are peanuts because the products give reputation and free advertise for your company.
I suppose that's one way to look at it. Another (mine) would be that I spend an average of well over an hour a day on these forums, being as helpful as I can; at least 500 hours a year. My current rate is us$125/hour, so that adds up to $62,500 year. For which I get more than you know. It's a good investment. But it doesn't require me to read and try to analyze your log files. That would be what I'd call a
value added service 
.
more.. of course if is the main core of your business you need to stay informed about all problems who can appear on DA.
Actually I hire people to do some of that for me.
(that explain the time you spend on forum)
Not really, but it's a good simplification, if you must.
just one advice from a business man to a business man dont advertise directly your products or services, let the users find you.
My advice, one businessman to another would more likely be something like
don't antagonize your possible clients, your friends, or your enemies. Just because we're all humans, and all of us from time to time are most likely arrogant, doesn't mean it's good business to consider the arrogance when it's brought to our attention.
If I or other person search for comercial services nothing better than a friend recomend your services as the guy who solved the small problem we have someday and have a company focused on DA products.
From time to time, when no one else has responded with a response, and I'm asked to help, if I cannot because it takes too long to do it pro-bono, I offer my services. I don't see a problem with that.
I sincerely apologize if I offended you, and I suppose I can apologize in advance in case I offend you in the future. Because I really don't intend to stop offering help, even if I must charge for it, on the DirectAdmin forums. My responses are always within the forum guidelines.
