When I started to produce software we licensensed exe modules to customers and everything was fine. We where able to reinvest revenues to develop new more productive methods and technologies.
But then somebody (probably either hippie or communist) becomes with the idea, that everything should be free and open source. And everyone suddenly wanted to be programmers having no talent at all.
With the Internet they even find customers who really belived that Internet makes them quickly rich.
Then it comes Google to save the world telling to programmers that they could run their ads with the software and still make money. Without knowing, what kind of ads will be shown, how much can I expect from the click and what could be my average click thru rate, its impossible to write any decent business plan even.
So far I have find out that raising money in the street is much more profitable option with better conversion rate and better earnings.
From Google I could get two to twenty US cents per click as people in the street are usually giving me average 1 EURo.
So why I should spend my time and talent to produce new and innovative intellectual property?
