1) Vivendi doesn't even own Blizzard anymore.
2) This analogy is convoluted and not helpful in any way shape or form.
3) 10 year old game that is designed to have constantly incoming new content isn't the same game it was 10 years ago, users around the world are shocked, news at 11. In your (very silly and not at all actually analogous) analogy, the restaurant is so old, the original chef has probably retired by now.
4) I hated sushi 10 years ago and now I love it. This is relevant to this thread but you can connect the dots fine without me trying to shoehorn it into another analogy.
