This appears to me the same case as a user downloading a proprietary=20 driver/firmware at some vendor website, accepting the EULA, then using=20 the driver within a QEMU VM. No close source blob are redistributed, but users can still run them,=20 and both party (the QEMU project, and the users) are legally correct,=20 right? But IANAL.
