It's very possibly a "rescued" fox that has been hand reared, or become used to humans around it, and has then been released.
If intended for release wild young animals should be fed literally at arm's length, with the person out of sight e.g. behind a screen, but many poeple can't resist playing with and handling the cute babies, which is very bad for them when they no longer avoid people once back in the wild

It can also be bad for people as some of these animals are then more inclined to stand their ground and bite people if scared or challenged, rather than nervously run away
