I don't care what the law says; the law says nothing about morality. If someone puts a piece of software on the internet and asks a reasonable price in return then you should just pay, and bypassing that is "piracy" and immoral. This isn't Microsoft Windows that you're forced to use due to their predatory (and illegal) business practices – which are mostly a thing of the past, but still has large effects today – by which Microsoft "earned" an ungodly sum of money.
