No, but luckily you have the legal right to change your VW engine with a Ford engine if you really want to.

But in your analogy, your VW would only allow VW gas sold by VW at VW filling stations. And the only two types of cars on the road are VWs and Fords, and each have their own filling station.

Now imagine you live in an area where only VW owns gas stations, they lobby the government and explain for the safety of the citizens they can't allow you to use any gas from anyone else, and the closest Ford station is 100 miles away, and you already own a VW.

I could tell you, "hey, you bought into the ecosystem, and you can leave any time".

And you would tell me I'm being unreasonable, and fight your local government to allow 3rd party gas stations.
