Honestly, it's all over the map. Depends on the reason for sale and the reason for purchase. They are looking for "synergies" and a very common one "you already have this thing, so you can cut it out of this company after you acquire and use yours". It is very possible that Epic had plans that involved hyper-growth, now realized those are not going anywhere, and is happy to demonstrate that a chopped up Bandcamp is a good deal.

I have literally done diligences where part of our role was to weigh in on how much could be slashed, which is not very pleasant, but like I said, when the growth was dumb in the first place it can be the right call.
