Anthropic cut off OpenClaw's 210,000-star developer community from Claude Pro/Max subscriptions — effective April 4 — while a researcher used the leaked Claude Code source code to uncover a zero-day that silently disables every security deny rule with a single padded command, and Google dropped Gemma 4, four open-weight models that rank third on the open-model leaderboard under a commercially permissive Apache 2.0 license. Anthropic Kills Claude Subscriptions for OpenClaw and Third-Party Agents Starting April 4 at 12 PM PT, Claude Pro and Max subscribers can no longer route usage through third-party harnesses like OpenClaw, the open-source AI agent framework with 210,000 GitHub stars. Anthropic's head of Claude Code, Boris Cherny, explained that "our subscriptions weren't built for the usage patterns of these third-party tools," citing compute and engineering strain. Users must now either switch to pay-as-you-go "extra usage" billing or move to the Anthropic API, which charges per token. Anthropic offered a one-time credit equal to one month's subscription fee redeemable by April 17 and bundle discounts of up to 30%. OpenClaw creator Peter Steinberger said he and board member Dave Morin "tried to talk sense into Anthropic; best we managed was delaying this for a week." The move effectively redirects a large category of power users — who had been running automated workflows on flat-rate plans — to metered billing.
