Add the following to your filter list for uBlock Origin:

kbin.social##article:has-text(/Elon/i)

kbin.social##article:has-text(/Musk/i)

EDIT: Here’s a version for lemmy users, just remember to replace the domain with your instance.

lemmy.world##.post-listing:has-text(/Elon/i)

lemmy.world##.post-listing:has-text(/Musk/i)

Edit2: Fixed case sensitivity.

I feel that, which is why I forked a tampermonkey script to replace his name globally. This is nice because it covers every site, which makes reading articles on WaPo and NYT much less irritating. Here’s what this thread looks like on my end, for instance:

And the script itself:

// ==UserScript==
// @name         Text Replace
// @version      0.1
// @description  Text Replace
// @author       SiameseDream
// @include     *
// @grant        none
// @namespace beepboop
// ==/UserScript==

(function() {
    'use strict';

var replaceArry = [
    [/ Elon Musk/gi,' the biggest twat on the planet'],
    [/Elon Musk/gi,'The biggest twat on the planet'],
    [/ Mr. Musk/gi,' this dipshit'],
    [/ Musk/gi,' this dipshit'],
    [/Mr. Musk/gi,'This dipshit'],
    [/Musk/gi,'This dipshit'],
    // etc.
];
var numTerms    = replaceArry.length;
var txtWalker   = document.createTreeWalker (
    document.body,
    NodeFilter.SHOW_TEXT,
    {   acceptNode: function (node) {
            //-- Skip whitespace-only nodes
            if (node.nodeValue.trim() )
                return NodeFilter.FILTER_ACCEPT;

            return NodeFilter.FILTER_SKIP;
        }
    },
    false
);
var txtNode     = null;

while (txtNode  = txtWalker.nextNode () ) {
    var oldTxt  = txtNode.nodeValue;

    for (var J  = 0;  J < numTerms;  J++) {
        oldTxt  = oldTxt.replace (replaceArry[J][0], replaceArry[J][1]);
    }
    txtNode.nodeValue = oldTxt;
}
})();
