My guess would be that it’s relatively quick for them to do and it allows them to bring the Witcher 3 back into the public eye whilst also getting some good will from the active community. Bet they announce another Witcher game release soon.
I trust they did their best.
I also trust that any sufficiently tech savvy individual will be able to bypass that system. It only takes one person to pull it off and then it’s public knowledge. Sure, they’ll fix it, and then someone will do it again.
Small companies can’t afford to take that risk and larger companies won’t want the hassle.
It’s a shame too. I liked Unity more than Unreal. Oh well.
