It's a valid question, but does it matter for anyone except the dev team? Bun is open source, so VC-backing is mostly a helpful jumpstart. If they find a viable business model – great, development can be funded in perpetuity. If they don't, development was funded for a while by someone else's money and then Bun is just like any other open source project that lacks direct funding (most of them).
I think it does matter. Open-source software can still suffer from "enshittification" when there is constant need to generate profit. Fortunately it is open source, so it can be forked when things get bad, but even then there still may be lots of tech debt to undo.
Right...but if you're going to fork it and create fragmentation, then we might as well go back to Node which has at least been stable for the past few years.
