Really? You think if I recommend emacs to someone using IE6 and they go view the site and it fails to display, that will somehow make them 'see the light'? I suspect the complete opposite is true and, hence, why gnu support browsers that aren't 100% GPLed.

Nobody is saying that it is practical, but GNU aren't known to make their stance on practicalities alone. GNU are known for their ideological purity, and a lot of people (some even quite grudgingly) admire them for their consistent stance.

I'm sure they've addressed this very issue. They almost certainly just write to the standards and don't bother putting in any browser-specific hacks, which is pretty much the best way to do things anyway, IMHO.

I saw at least one IE6 specific hack in their pages.

You seem to be in agreement with the person you're replying to. They're saying that there's a compatibility shim so that more IE6 users can 'see the light'.
