IANAL, so I cannot answer this > question. It's not morally grey though. The GPL is designed to attempt to prohibit this and as a copyright holder in QEMU, I choose[1] to use the GPL specifically to prevent this. QEMU only exists because people have contributed back their improvements to the project. Not contributing back means that you are only taking from the community withing returning anything back. Only your lawyer can tell you whether this is legal or not, but it's certainly unkind. [1] I == Anthony Liguori, not IBM. I began my involvement in QEMU long before IBM paid me to be.
