kling is the creator/head of the ladybird browser. dhh is the creator of ruby on rails, but he’s now working on omarchy, which is basically just a collection of dotfiles for arch but people love for some reaso (personal rant).
the reason that their views are important is because a lot of tech companies, even ones that were previously reputable like framework, have been pouring a lot of money into these. this is especially relevant for omarchy, since afaik dhh is the only person working on it, making donations to omarchy basically be direct donations to dhh himself.
while kling has done some questionable things, dhh is basically just a straight up fascist, which really puts the principles of the companies giving money and promotion to him (like framework) into question
if it’s any consolation, native danish speakers don’t think about it like this, you just kinda memorize what each multiple of 10 is called. although the etymology does appear a little when using ordinals, e.g. 72nd in danish is tooghalvfjerdsindstyvende (two and half four twenties), but i think most young people would just say tooghalvfjerdsende (72 + ordinal suffix)
