But they're doing it under the banner of the libre software movement, whose raison d'être is free (as in liberty) software. Having political strings attached is antithetical to the movement.
The lack of political literacy and self-awareness in this thread is embarrassing.

I believe you may have a rather narrow notion of what politics are.
In my book, politics is the art of making choices when your ability to predict the future is limited, and therefore the willingness, courage and fortitude to make choices under uncertainty.
Under that definition, they're making a choice, one that materially and obviously can't be backed by sound reasoning or logic (because predicting the future is hard), that's politics.
Libre software is a political movement. And it makes sense for libre contributors to be highly skeptical of a tool that may or may not violate copyright, profits from the work of other libre codebases and is controlled by tech giants.
