It’s been fun watching the unlikely rise of MCP as a standard, which is open and messy in a way that mimics the dynamics of the good parts of Web 2.0. Maybe something interesting will happen!
I would only add that this is a valid assertion about all of the major platforms funded by big tech. (Whether they are framed as non-profits or B corps or not.) It need not be intrinsic to the technology, but we do not yet have any meaningful large-scale counterexamples.
