That's a pity. Bandcamp is my go-to for getting DRM-free FLAC files straight from the artists. The site was a little crusty but they were a huge benefit as a tech-friendly independent music community.
Oh, and there's no "open in app" feature on the site, or a "copy URL" feature in the app.
Otherwise, I share the sentiment that Bandcamp itself is (was) a great place to buy indie music in high quality, and that this feels like the beginning of the end.
From a dev perspective of someone who's worked with several Epic tools I'm not immediately worried about what seems to be more of a technical acquisition. Historically they do seem to actually leave their subsidaries hand-off, integrating their tech into Unreal instead of absorbing it entirely. I imagine the extend of the ramifications here include some way to expand Unreal's Asset store to include music or SFX (which artists can opt into offering on the asset store).
