I'm openly aligning with DHH with regards to Linux, Apple, Rails and webdev in general. I suppose scores of other people do the same. The other stupid or controversial things he rants about are not really of much interest to me.
Same goes for Musk: I think electric cars, rockets and fast satellite internet are cool. He posts and does stupid things, most of which I don't agree with. But I wouldn't set my neighbor's Tesla on fire because of that.
DHH's is kind of the hero that the Linux desktop needed. Controversial, loud, enthusiastic but not without flaws. We need someone to balance things out -- almost everyone else with an audience out there is shilling for Apple.
I have the freedom to scream "FIRE" in a crowded building when there really isn't a fire, does this mean I should be excused from the consequences? DHH has the freedom to post racist and intentionally divisive BS on his own site, and we have the freedom to let people who care about being anti-racist know to stay away from him and his work.
