> Why does anyone need to ask Tesla anything? What does anyone need to pay?

The comment is not about Tesla cars using non-Tesla chargers; it is about non-Tesla cars using Tesla chargers.

If other car makers want to use Tesla's network they would have to pay their share of the costs of maintaining and expanding the network.

At the moment Tesla's Superchargers are available only to Tesla cars even though many other cars use Type 2 and they now have CCS connectors. Tesla have several times said that they would consider opening up the system to other manufacturers cars if those manufacturers were willing to pay their share of the costs which most likely would be less than the cost of creating their own network. But, no other manufacturer has taken them up on it.

None of the charging networks you mention were set up by the car makers. Tesla's network is part of the package when you buy a Tesla, or at least it was, and is again, for the S and X. It is a selling point that the chargers just work. They have no user interface, you just plug in and it works. You connect your credit card to your Tesla account and away you go. No need for dozens of apps and RFID cards. Every other charger I have tried to use has been significantly more trouble and often simply would not work. Even those that are free in Tesco supermarket car parks (provided by a consortium that includes VW) need an app on your mobile to get more than 15 minutes of charging.
