I care not for this explanation and opinion. If someone is unable to work on practice problems without just looking up the solutions that is really their problem, not mine.

That just translates to giving the middle finger to self learners.

I have not yet seen a decent explanation for withholding sample solutions/explanations. It usually just boils down to "I want this to be only for university professors to give homework from and I am of the opinion that university students lack the minimal discipline to work on problems in their own"
