Open source coders provide software development and support services for free. They’re not providing a physical product.
I feel like you’re stuck on some ephemeral concept around what a service is.
Human beings provide a services for a variety of prices. A business provides a profit generating pipeline.
And we all see how those can vanish over night. Or just decide to kill things coughgooglecough
Seems like a contrived line in the sand, IMO
