Bandcamp has been successful because of the trust they have within the internet music community. It’s not a very complicated product, but people buy music there because the whole thing feels like it’s a part of the music scene, not the tech or business scene. Given that the Daily is well regarded in that community, I highly doubt those six writers, who were likely paid significantly less than the median staff member, were the problem here. Even if they didn’t have the purely trackable ROI, they were a huge part of the platform’s only moat: its goodwill with the artists and listeners who used it.
I would also add that Bandcamp was pretty publicly profitable prior to their sale to Epic. Given that they didn’t significantly grow the staff after the acquisition, they would have had to make huge blunders in a very short period of time they owned it. So at this point we’re talking about laying folks off purely for better looking numbers, not really for sustainability.
