Private variables with public view functions

In the Openzeppelin ERC721.sol contract, there are private variables introduced:

// Token name string private _name;  // Token symbol string private _symbol; 

These variables are then assigned a public view functions to display their content:

 /**  * @dev See {IERC721Metadata-name}.  */ function name() public view virtual override returns (string memory) {     return _name; }  /**  * @dev See {IERC721Metadata-symbol}.  */ function symbol() public view virtual override returns (string memory) {     return _symbol; } 

Why are these private instead of public? Nobody can change the values in either of the cases, as mentioned here.
