There's no contradiction between desiring free speech in the public sphere - which is what Musk claims he wants - and not wanting to associate yourself with people who support certain speech, which is what Musk has done.
The comment I replied to before is a non sequitur, this doesn't mean what Musk is doing is right, simply that mindlessly upvoting a Trump-rally-tier argument is not conducive to anything good.
Eventually HN will become reddit and we'll just upvote "our side", regardless of whether the argument has merit.
