This is just a guess from a UE game developer, but:

a) Epic makes Unreal Engine and runs an asset store that includes sounds and music. Why not include bandcamp and their huge catalog in that store?

b) Epic makes Fortnite, which has tons of music industry tie-ins through purchasable emotes, song tracks, and free in-game concerts. Bandcamp sounds like a great avenue to expand existing agreements to sell music through Fortnite.

c) Epic also acquired Harmonix, which is the original developer of Guitar Hero and various music game spinoffs. Who knows wtf they're doing with Harmonix, but Harmonix+Bandcamp seems like an easy business strategy. "Buy this album on bandcamp and get it in the new Harmonix game too", and vice versa.

Epic has their hands in an awful lot of pies these days, and their layoff statement seemed to be a straightforward admission that their eyes were bigger than their stomach.
