BMW are entitled to ask what they want for the team. And I doubt Sauber was doing them much of a favour, as he had a twenty percent cut of the team and still felt attached to it. My problem with BMW is that they are not behaving in a sport manner. After being incredibly in favour of things such as KERS and shouting from the rooftops about how evil the FIA was, they then decide to leave Formula One high and dry. Besides, from a business point of view, it makes sense to do something similar to Honda: find somebody to take the team off your hands, so you don't have to pay redundancy and decommissioning costs etc.
