Damm, I thought the concern and the problem was with those poor little kids who bought that new Xbox without knowing what they were buying...!!!


LOL. It's funny that you're asking for more pressure and action to preserve the past and present catalog to the people of a platform where your have the better access to that catalog, and not to the other of the more closed platforms whose efforts in BC over the last decade have been disappointing (including charging for updates and charging subscriptions for BC for older consoles).
Then, PlayAnywhere, whether you like it or not, is a pro-user service and worthy of praise. It's not perfect, but it's improving day by day within its capabilities. Is a great proposition for users with multiple plataform.
In the next generation??? We'll see how MS resolves this issue. When there are many indications that they are working on offering BC even beyond their own devices.....at least you could be cautious in what you say instead of lecturing others about things that you then don't require on the platform you are using.
