This is the naive comment. It takes a lot of effort to start a company and make money off of something, even if you didn't make the original version. If people are willing to pay millions of dollars for software, and someone comes along and builds something that fits that demand, then why shouldn't they?
Some people make software for fun, or to help others. If my software helps someone make millions, then cool, good for them. Personally, I would certainly monetize free software I made if I saw the opportunity. However, some people might already be wealthy and want to play with their kids or something instead of chasing a new startup opportunity, so they shouldn't care if someone else makes millions off of their software. You are acting very arrogant when you assume everyone's values line up with yours.
