Actually the poster makes a good point about how when organizations excessively make acronyms, they can actually hamper communication and efficiency. I read the link, and I think Elon Musk makes some great points, so I don't think the poster's praise of Elon Musk should be criticized as a "fetisization", and I don't think the poster deserves so many down votes.

Although to be honest, I did have to look up "updoot" in the Urban Dictionary :), so to be fair I should say unnecessary use of urban slang can also hamper communication.

The military uses acronyms heavily. The seem to be still in business.
