The pejorative term, in the economic sense, tends to be reserved for rents obtained by gaming the system, rather than the usual kind that charges for use of property or capital.
Example: a utility company lobbies for a law requiring utilities to charge a junk fee.
Non-example: I charge someone to live in my spare bedroom.
Tesla is offering use of something they built (Superchargers, self-driving software, etc.) in exchange for a fee. They aren't gaming the system to force anyone to pay. You might not like the pricing model, but there's nothing economically wrong with it.
