Motivation for founders is a lot easier to understand than that of the acquiring company. What on earth is Epic going to do with Bandcamp?
Licensing As A Service is probably a neat thing if it can be done at scale on par with the Unreal Engine Marketplace. But a lot of it boils down to "imagine if we could make IP law straightforward" which is somewhat of a moonshot.
Also could be a source of creative content to generate NFTs, maybe even tie that to licensing of music used in game livestreams.
but "fortnite" by epic already had concert/online experiences. They've been pretty fun. Maybe getting band camp allows them access to artists they didn't have before?
