Another non-iOS developer here. It was absolutely not clear what you meant with a single word reply, and one that honestly looked like a typo or some kind of insult (short + -ist) I didn’t get.

I completely agree with you that if I had wanted to I could have put in the effort to decipher the meaning of the post. However, the post left me with absolutely no desire to decipher it's meaning, so I did not. If instead the author had written simply "I use tuist for that" the meaning would have been immediately clear for someone like me, and I would have been much more likely to look up the product.

I don't mean to imply that there is some sort of "should" to this. The author is not required to want their meaning to be understood, even though I'm not really sure what other purpose they would have for posting. But I do think that this class of miscommunication is both common and reasonably avoidable by building up a bit of a mental model of the intended audience. I was trying to provide anecdotal evidence to build up that mental model.
