The value in open source code was never the code. It was the trust that was created around it that it becomes a place for useful innovation, for trust, for vetting, for keeping dependencies low.

I can build my own curl in a week, but the value that curl gives me is that it's a multi decade old library, by a person that has dedicated his live to keeping the project there, keeping a quality bar etc.

The value of curl is not curl, it's the human behind it.
