I wonder what those people do all day, when they just Java and Go on server side, as per job offers.

When compared with Oracle, IBM, Microsoft and Google efforts for Linux support for their ecosystems, I really cannot see they work at all, given their output in the last five years.

I think they are understaffed. I know for Swift on Windows, there is exactly one person driving that effort last I checked.

The Swift Linux team might have 2-3 people. And knowing Apple, that might not be 100% of their time.

Which cleary shows how much that matters to Apple.

Well, my argument is that it matters more to them than Objective-C did.

I've been paying attention to the GNUstep project periodically since 2004, and I can't recall Apple ever supporting the project.
