How do we know about Schumacher? I'm sure I'd read somewhere that he was able to show signs of awareness and the latest interview with his wife mentions him being part of the family, and them doing therapy with him etc.
ETA in fact there's another article today about him- Jean Todt (his ex-boss at Ferrari) claims that they watch F1 races togetehr- definitely implying that there is consciousness there. I guess it could just mean that he just sits in the room while the TV is on, but it is an odd and disigenuous way of phrasing things.
Truth is it has been so long, not many people are actively waiting for health updates. It is odd of his family to volunteer ambiguous comments about his condition.
