Sdks/libs, especially open source sdks, were never about gated knowledge. They were about the providing company making it as easy as possible for you to integrate. You would not need to know the idiosyncrasies behind api retries, paging, rate limits, auth flow, and on and on. The third party developers needed a resource, they call a method and get it. Open source libraries especially are about pooling knowledge, not gating it. This is propaganda for pooling that knowledge inside a service you have to pay to use, and instead of developers all using and improving the same codebase together, they have to spend money to rewrite the same code repeatedly. This is AI companies further trying to undercut open source because it’s free.
