Why do they claim that Word ditched its equation editor? I believe I’m on the latest Word and it certainly still has the editor.

Word’s equation editor is hands-down the best WYSIWYG equation editor I ever used. The results are beautiful and if you want a tilde you just type a f*ing tilde instead of spending an hour figuring out which combination of packages and fonts will cause LaTeX to grace you with this standard unicode character.

I guess maybe MS discontinued the old plugin equation editor (which was terrible, agreed), but the built-in one is still there.
