Simply rebuilding code, without adding value or changing it in any way, represents a real threat to open source companies everywhere. This is a real threat to open source, and one that has the potential to revert open source back into a hobbyist- and hackers-only activity.

I agree that it's particularly damning, but for a whole different reason. Anybody who considers "a hobbyist- and hackers-only activity" a "threat" to "open source" fundamentally no longer Gets It and is themselves an enemy of Free Software!
