I think they noticed cos Zayn on iTunes doesn't say Simco it just says RCA Records, a division of Sony Music Entertainment check iTunes
From what I hear the “clean” and “explicit” versions are different, and one retains the copyright to Simco and the other does not.
No matter, because the cat’s out of the bag now. That “℗ 2016 Simco Limited” unambiguously confirmed everything that everyone who said that Zayn’s “leave” was a stunt already knew. Touchdown, goal, score, one point, 15–love. Game, set and match. Game over. The end. Finito. Fin. Deuces. Bye Felicia.
I really can’t thank everyone enough for the outpouring of support that you’ve offered @mule-madness and I. To see how many lives this little old mule touched, and how many smiles she passed out has touched our hearts and brought many good memories back to us. So thank you, all of you.
