The reasons why any animal eats a particular organism is never clear. A top reason why Nudibranchs might eat 'toxic sponges' is that there was not much else available to eat and it was easy to eat the sponges. These sponges were a niche that was unfilled and the Nudibranches adapted to take it. The sponges are still partially toxic to Nudibranchs! They often have specially lined stomachs to protect them from the sponges sharp spicules and the toxins from the sponge accumulate in them. When a predator tries to eat a nudibranch it gets a nasty mouthful of these toxins.
