I haven't used Alpine much, but it seems targeted at server and embedded usecases. Void is decidedly a desktop distribution, and feels like Arch with a more powerful set of package tooling and runit instead of systems. From my limited experience, I'd be more surprised by someone running Alpine as their main OS than OpenBSD, whereas Void is almost accessible by comparison.

I'm sure it works well for that purpose, it's just rare to see.
