It reminds me of Tehillim 151. There was a guy who didn’t find any reference to Galyas in Tehillim. He decided to help out David Hamelech and fill in what he obviously forgot. Naturally, one look at his job shows such a cheap shot. You can find it in a thick Sefer called, Sefarim Chitzonim.
The problem they had with Ben Sira is that his Lashon sounded like a Pasuk. This ‘passage’ doesn’t have that problem.
