Why didn't Travis Barker produce Bring Me The Horizon's new single "DiE4u"?

The song starts with some super chill, Shawn Mendes style vocals and immediately I'm like, “oh no, they're about to piss everyone off.” But then Oli rips into a scream that lets you know everything's gonna be alright.

The chorus is very poppy with lots of electronic elements, while the verse has enough driving aggression to make everyone happy.

The music video is basically a mini-movie which is cool if you're into that style, it's not really my bag though.

Overall, the song is definitely a future smash hit, breaking over a million streams in the first day, but I'm still left with one burning question; why the fuck didn't Travis Barker just produce this?!
