GNU/FSF is totally at fault here beginning with not actually developing an usable kernel. But in the case of a microkernel like Hurd, wouldn't it just be easier for proprietary drivers? Still, I think max freedom enforcement may be a good thing as to press companies to adopt that. However, GNU not having control over kernel development is what allowed much o kernel surrounding proprietary blobs to take place, and then needing something like Linux-libre.

In any case as exemplified by the exception and the Purism case, GNU/FSF is hypocritical and it shows.
