@tante I think the closing line of that email summarizes the situation even better: this person (and many others) do not see free software as an emancipatory project. I don't think it's useful to pretend they do not stand for anything, when their stance is so clearly that liberation does not matter as long as the software is free.

(This is not to say never to contribute to these projects - there is no ethical consumption under capitalism and this also applies here)
