Playstation is a subsidiary with a lot of independence, so I don't see it as an issue. Different subsidiaries also don't necessarily share the same values/ideas.....if anything it's usually the opposite and they can clash as a result.
Companies aren't monoliths, they're not a single mind. Unfair to drag other Sony departments for Playstation's move especially when clearly those department support physical media. Be upset sure, but be upset with the right one.
I like big butts and I cannot lie.
