There’s this thing in business called competition. I know it can be annoying when it happens to you for the first time, but it’s the way it’s meant to be there. When someone enters your particular market segment with a competing product it’s not called “copying” it’s called “competition” or possible “free trade”. Browsers didn’t exist once and now those nasty opensource developers went and copied the idea and have put the original company out of business. And those damn JEdit folks blatently ripping off NotePad which itself was just a rip off of TextEdit which was just a rip off of MacWrite.
