My thinking on Anthropic has been shaped most by Ben Thompson and Peter Steinberger. Peter created OpenClaw so is affected by closing models to third-party apps. Ben has an article today after the Fable fallout:

…given that they think only they should be developing leading edge AI, they by extension think that only they should have final say over AI generally. When you further combine this realization with the company’s pronouncements about AI’s ability to conduct all economic activity, you realize that Anthropic’s leadership effectively wants to have power over everything and everyone.
