Well it's not technically the main focus of FLOSS, but consider that that it was invented to work around the failings of Capitalism. The whole idea of Software Freedom goes against the Capitalist ideals of "Put a price tag on anything and everything you possibly can".

I think what has happened is that as more marginalized people have 'woke' to the fact that Capitalism is oppressing them just as much as the Patriarchy, the 'Libre' aspects of FLOSS has become more appealing to them.

It probably wasn't the intention of Linus Torvalds to create 'woke' software, but by following the principles of the Free Software movement, he did it anyway. Though I think even he might be coming around :)
