The Linux community had chosen to actively ignore the IETF for about ten years. 
This only changed relatively recently.

And, FWIW, Hagen & friends' DCTCP implementation for Linux is based on the 
initial versions of our DCTCP I-D, and arguably wouldn't have happened without 
it.

CUBIC has of course existed in independent implementations before, but it is 
unclear if the BSD licensed ones were actually only done based on Injong's 
paper.

I guess we're getting on our soap boxes at this point? :-)

But I don't define "the efforts of this standard body" in this way. I remain 
convinced that textual specs are required. Code is a nice addition, but really  
only useful if it can be rather freely used - which GPL code can't.

I agree that this is a problem. But we can't all start to use GPL for 
everything.

That's a stretch. The alternative to GPL is not closed source. There are other, 
friendlier OSS licenses around.

As much as I want to agree, if you work for a commercial entity, the risk is 
just too great (cf. the GPL clause regarding implicit licenses to patents).

Sure. But the risk is incorporating code that may be GPL-tainted into non 
GPL'ed code bases. In other words, it's not the code itself that is a risk, it 
is a risk for the codebase it is used from.

That's certainly one viewpoint.

Sorry, but I really don't understand how this discussion is not trying to help 
with just that?
