Take one glance at history, and you'll see that having a sovereign ethnic homeland is crucial to that "freedom to exist". So you're wrong on both counts - they are also taking a stance for the latter, and the two freedoms can be separated. Distributing FOSS does not require one takes a stance on every ethnic and political conflict on Earth. The GNU manifesto never once talks about the occupation of Tibet. This "cannot be separated" is nothing but a cheap attempt to attach your own cause to some other, more widely accepted cause.
FOSS never was about the right of the distributor. It’s been always about protecting the user. The way to do it is to give the users a set of rights that cannot be revoked.
