Jeez, no wonder there was no input. That colour scheme (orange, red and black text on red-brown background) on his forum would have stopped me ever returning.

The short answer, right from the horse's mouth is: "We're not aware of problems in Slackware aside from the two listed above: there's no clear policy about what software can be included, and nonfree blobs are shipped with Linux. Of course, with no firm policy in place, there might be other nonfree software included that we missed." (from the thread posted above).

That's pretty close to a full endorsement without actually getting one.
