The title is heavy clickbait. To say I just bought a Porsche when it was actually a Volkswagen is also wrong. Just because they belong to the same owner doesn't make it the same brand.
However it was more complicated than that. Porche owned 50+% of Volkswagen at the time of Volkswagen buying them. Porche got over extended and leveraged buying Volkswagen . The management family is closely connected since the start and at the time in early 2010s 20% government ownership rule was just getting stuck down by European courts .
