GitHub Copilot token billing shock: devs report 10x-50x cost spikes after June 2026 switch

GitHub Copilot's June 2026 switch from flat-rate to per-token billing caused immediate cost spikes of 10x-50x for teams, with one user burning 54% of a monthly quota on a single request and the community discussion receiving 958 downvote reactions vs 24 upvotes. Simultaneously, the Claude Code source leak exposed 512k lines of proprietary scaffolding code, triggering mass debate about AI coding tool transparency and vendor lock-in. Teams now juggle three or more AI coding tools with zero visibility into normalized spend across them, and no cross-vendor spend web app exists that ties cost to actual output like commits, PRs, and repos.
