The Subsidy Was Never About You

Anthropic has progressively restricted third-party tools from accessing Claude subscriptions, culminating in a May 2026 pricing split that classifies usage through non-Anthropic surfaces as 'programmatic' (billed at full API rates) while keeping usage through Claude Code and Claude.ai subsidized as 'interactive.' The post traces a five-month timeline from silent OAuth blocks to formal ToS changes to billing enforcement, arguing the real motivation is routing valuable training-signal interactions through Anthropic-controlled surfaces and improving unit economics ahead of a reported $950B funding round — not billing simplification as officially stated. Developers who built automation workflows around the old $200/month plan now face 5-10x cost increases, and many are migrating to competing models.
