I like the "carrot" side of this, where a couple of hundred titles will be available at a discount. That's an important step that some music distributors found works well against piracy, take down as many barriers as possible in front of people wanting to buy the product in question, while punishing the most egregious offenders (largely Chinese companies making a profit from piracy in this case, near as I can tell).
I doubt this will have much direct effect on scanlators, other than removing some sources of free raws.
