That's...not a common carrier at all. Traditionally, a common carrier is "a person or company that transports goods or passengers on regular routes at set rates." So traditionally, a rail line is a common carrier. A pipeline is a common carrier. Air freight and truck shipping, kind of, but you're then getting away from that "regular routes" kind of thing. This was then logically expanded to things like telecommunications, since they're essentially transmitting data along regular routes aka the actual telephone wires.
A big thing about becoming "common carriers" was this idea of regular routes. Competition gets challenging/impossible when there's really a single route for some things. There's really only going to be one set of rails connecting towns. There's not going to be a bunch of different companies stringing telephone wires to everyone's houses. There aren't going to be a lot of fiber runs through a neighborhood. These things are all common carriers and are natural monopolies.
I can go buy an apple at the grocery. I can eat that apple raw. I can turn it in to apple sauce. I can bake it in a pie. I can juggle with it. I can give it to a friend. I can donate it to charity. The fact I can do all these things with it does not make the apple producer or the grocer a common carrier. It's entirely unrelated.
The person I was replying to was stating any company with 10% market share in any kind of metric should be considered a common carrier. Nike has more than a 10% market share in total revenue of sport clothing. So they say Nike should be a common carrier. This makes no sense to me.
