I don't see why it should fair a single-developer to copy an idea from a company but not the other way around. What does size have to do with it? And remember, we're still not talking about copying code or violating patents -- we're just talking copying a simple idea. Something that still requires work to implement. Copying ideas is the foundation of every industry. Is it immoral of you to build a better or cheaper car because Henry Ford got there first? Airplanes? Windowing systems? Command-line shells? Bicycles? This is frankly just BS. You cannot hold ownership over an idea -- it's just not possible. And when you release your idea from your brain into the world, other people will learn it. You can't force them to not use your idea for themselves because you thought of it first.
