Tan is merely the owner until the next one comes along, and the one after, and the one after etc. Fans remain (well some will). He's the guardian of the biggest football club in Cardiff and the surrounding area and makes his money at the club from those who live and breathe the club, who support it week in, week out.
If I don't like a supermarket, I have choices on what to do. It's hardly the same with a football club when it becomes a part of your life and identity. A part of every football club belongs to the fans.
