Some feel that developers' rights can be disregarded with impunity. We call it piracy however benign the perpetrators motives may be. We should add that in another dubious case this same person made internals of another's commercial product publicly available on the web. The situation has gotten completely out of hand for commercial developers. PSS, for example, was able to get nine renegade sites shut down.
Incivility is rampant in the message boards and forums.
Because people take pride in their work. Sure, some developers want to be a commercial success, but think about the human angle. Whether commercial or freeware, the authors' reputations matter . And the forums are a very public place. I don't want to be involved in Avsim's or anyone else's politics.
