I do it a lot, do me a favor and don't attribute it to Sam Altman since some of us have been doing this for a long time. If you don't like it, you don't have to read it, but you also don't need to be patronizing and close-minded about how others choose to express themselves.
I think writing like this is disrespectful to your audience since they have to put in extra effort to parse your text. If you choose to express yourself like that, fine, but it's not patronizing to point this out.
Maybe you're not the intended audience! :)
