@Suiseiseki Yeh, the company that used GCC as a base for their C++ compiler used to only release proprietary software, but they released their compiler under the GPLv2 (i think), i think one of the reasons they even did that was out of annoyance from customers complaining the source libraries they paid for wouldn't build with some proprietary compilers and they gave their customers that gpl compiler so they would shut up, or was that a different language?
