Of course, you legally aren't obligated to attribute. There may even be valid ethical reasons for not wanting to attribute. It's not a good reflection of character to make immature jabs and denigrate the person asking as a 'junior developer', as if that's a personality flaw. All you need to say is: Thanks for bringing this up, but I am not obligated nor feel that I should attribute. Thank you.
