First, my background....
I created a program many years ago called the Holographic Screen Saver. Originally, I wrote it for myself but after the advice from friends and family, I decided to sell it. The license was shareware and I'd give people a 7 day trial period, afterwards which they would need to purchase it for a price.
While I never really made a lot of money, I did make over a few thousand dollars. Over the 2 years I had the website up, I actually spent around a few thousand dollars as well. Merchant fees, website hosting costs, domain name registration, bank fees, reversal fees, etc.,.
So basically, I wound up really making nothing.
Well, about a year into my 'software biz', I found that many sites had a crack to bypass the registration process. At first I was angry but then I thought about it a little more and realized that my real customers would never have thought about doing that. One customer actually paid me twice purposely because he thought my customer service was the best he ever had.

I guess my view is that I created the software once and getting paid eternally for my single creation (man hours, money spent) seemed strange to me. I kept thinking how it would be strange if I made a million dollars off a program I only spent a year making and a few thousand dollars on, talk about a markup!!
I am now getting into a manufacturing biz and my feeling is kinda like this...
Selling software and selling products are not equivalent.
Having software copied illegally and having products stolen are not equivalent.
If someone wants to steal your software they...
a. Probably would never have purchased it in the first place.
b. Won't harm me in any way.
If someone wants to steal my product they...
a. Probably would never have purchased it in the first place.
b. Would harm me financially and possibly physically.
I don't think Copyright infringement is the same as stealing and quite frankly, I could care less how many people copy my screen saver without permission. I made money, more than I think I should have and had a great time doing it.
