The good news is that the downvotes aren't necessarily representative of the industry, in the sense of people who actually get things done. You'll notice that this change (see also the bit about being sponsored by Mellanox), the recent OpenZFS change, etc. were all made by core contributors to the projects. (It's also why the Contributor Covenant was fairly rapidly adopted by the actual contributors to so many projects, despite so many people being angry about it.)
But yes, the open source fandom is distressingly racist.
