Morally? That depends on the person. I think asking a piracy focused community means you’re going to get a heavily skewed set of answers that all veer towards various forms of “Not wrong” or “It’s good actually. Don’t even support the platforms that make the content legally available because DRM sucks” etc.
Generally speaking though, most older visual media releases no longer make money for anyone who worked on them directly. Use that information however you see fit. I know it changes how I think about piracy in general.
