Long story short, there is a lot o struggle between VW and Porsche. VW - especially it's employees who have representatives on the board - feel like the takeover is going the wrong way. Porsche has 12000 employees, Volkswagen - with its Audi, Seat, Skoda, Lamborghini etc etc branches - has >300000. Originally, everyone expected it to become a friendly takeover (since Porsche is family controlled and not so dependent on the capital markets) but it has become a rather sour relationship. I think Porsche wanted to send a signal that says 'give up'...
