OpenAI embraces the 'platform paradox' by selling API access to startups that compete directly with its own apps like ChatGPT. The strategy is to foster a broad ecosystem, believing that enabling competitors is necessary to avoid losing the platform race entirely.

Developers using OpenAI's API risk having their innovations copied. The company allegedly studies API usage to identify successful applications and then builds competing features, a strategy historically employed by platform giants like Microsoft and Facebook to absorb value from their ecosystems.

As AI makes it trivial to scrape data and bypass native UIs, companies will retaliate by shutting down open APIs and creating walled gardens to protect their business models. This mirrors the early web's shift away from open standards like RSS once monetization was threatened.

Anthropic's policy preventing users from leveraging their Pro/Max subscriptions for external tools like OpenClaw is seen as a 'fumble.' It creates a 'sour taste' for the community of builders and early adopters who are not only driving usage and paying more because of these tools, but also providing crucial feedback and stress-testing the models.

Anthropic's campaign risks poisoning the well for all consumer AI assistants by stoking fear about ad integration. This high-risk strategy accepts potential damage to its own brand and the category in order to inflict greater harm on the market leader, OpenAI.

Anthropic clarified that OAuth tokens from its consumer plans (Free, Pro, Max) are exclusively for its own website. Using these keys in any other product, even Anthropic's own Agent SDK, is a violation of terms. This move walls off its consumer ecosystem from developers seeking unofficial API access.

OpenAI's platform strategy, which centralizes app distribution through ChatGPT, mirrors Apple's iOS model. This creates a 'walled garden' that could follow Cory Doctorow's 'inshittification' pattern: initially benefiting users, then locking them in, and finally exploiting them once they cannot easily leave the ecosystem.

When one company like OpenAI pulls far ahead, competitors have an incentive to team up. This is seen in actions like Anthropic's targeted ads and public collaborations between rivals, forming a loose but powerful alliance against the dominant player.

The data that most of Anthropic's customers also use OpenAI refutes the idea of a zero-sum market. It reveals a sophisticated enterprise strategy: companies are not choosing one provider, but are building a 'best-of-breed' AI stack, leveraging different models for different tasks. The battle is for workload share, not winner-take-all.
