I'd assume the Bun people got a bit more than a thanks when Anthropic acquired them. :)

You also can't take your GPL code (unless you do CLAs with all contributors), convert it to closed source yourself and make a massive VC funded startup around it. Which is about the only other way anyone makes better money from open source than by just working for a big tech company.
