The moment a word is used as a german word by a german it does not really matter anymore where it's from, the usual mechanisms that specify gender apply. Which are the few fixed rules, then mostly "how do others speak", maybe a bit "how does the word sound". That's how foreign words become german words. There is no rule that loanwords end up as neutrum: Die Allee, die Paella, der Computer, der Laptop are just a few counter examples.
