Hard fisagree. Linux isn't political. Everyone has an opinion, it's obvious Linus would too. But I am pretty happy that his opinion is one I personally agree with.
Linux can be uaed by anyone though, and nothing stops far right activists (terrorists) from making a distro, which would still be Linux. There's a heavily religious distro too, but that doesn't make Linux as a whole religious.
Does that really make it totally apolitical though?. Like obviously it's not inherently attached to a wide reaching political ideology, but it still is political in the same way that any free software is kind of political.
I don't think we get to use cold reason to determine if something is political or not, just like a dictionary doesn't control the meaning of a word, nor does a small group of ants decide what the colony does next. If Linus came out as a right wing extremist, it wouldn't matter how apolitical the linux source code is, people would decide to distance themselves from him and everything he represents. Something is political the moment a society perceives it as relevant to their politics.
