please don't insult the FSF like that by comparing it to the LF...

The FSF might be unpragmatic and (thus) often horribly out of date, but it's neither opportunistic nor engaged in corporate bootlickery.

At some times it can even be dogmatic, but you can at least mostly depend on it keepig it's spine and vision!
(even if I partially disagree with it, as it's doctrine does not take political economy — and thus the root problem that is capitalism — into account)
