Would you describe it further? I don't see how coming to a subscription-based model makes it not piracy. I feel like I miss something there.
I died a little inside by remembering that I was there when their lifetime CS licenses were sold and that licensing servers went offline at least a dozen of years ago... On the other hand, it raises a question if breaking CS versions is a piracy if they are abandoned. There's no way to use them even if you are a paid customer wanting to install it on your new PC.
