I don't thinks words are being put into anyone's mouth, what was said was quite clear:
> while Git is made by anti-GNU people who do not believe in free software
As stated in above comments I would find it hard to believe Linus would not say that GNU is a valuable asset or software built strictly promoting GNU/FSF principles is bad ... but he's been labeled as anti-GNU for writing software that has a more permissible license. I don't see how this could be an even more "with us or against us" attitude.
You could argue the above statement is an overgeneralization of what the OP said to the whole movement. But there are plenty of thing that prominent individuals, who work on GNU and represent the FSF, have said that would support this attitude.
