Does anyone know the background of the decision to restrict commercial usage for the 64bit version? Seems strange to have the 32bit vs. 64bit versions licensed differently.
I'd imagine it's because nobody will want to use the 32-bit version for anything commercial, so there's no worry about it. If some company wants to use the 64-bit version commercially, then the team is going to want to have some say there in case the project picks up steam and really goes somewhere.
