> Hex-Rays did ultimately release IDA Home, but you have to sign up for an account to even find out what their hobbyist license costs.

And even then, IDA Home comes with some pretty serious limitations. It's not just a no-commercial-use version of IDA Pro; it's also a cut-down version with no decompiler, no batch mode, and which only disassembles code for one processor family (which you have to choose at the time of purchase, from a limited subset of what IDA Pro supports).
