Yh I mean Freud has his own problems but they're more due to the scientific status of his claims and issues with his methods imo than due to the clarity of his theory.

There's a difference between something being difficult, because it's densely but very systematically written, so that people are likely to not find it completely clear on first reading, and it being unclear due to the writer not making their terms, assumptions and the steps of their arguments clear. The latter is a problem they can be blamed for, while in the first case it is often possible for them to be clearer, but if it's because the content they are discussing is difficult, then it can't really be blamed imo. A text can be difficult and still intrinsically or internally clear imo, as anyone who studies mathematics finds out.

Some works are difficult and its unfair to demand that they make themselves clearer at the cost of not analysing relevant content.
