Real quotes from Reddit comments that inspired this opportunity

  • Are we gonna get our usage back? No? Then I'm not subscribing again
  • refund those who used extra usage to compensate for the bug
  • no official announcement about this totally-not-a-minor change and no limit reset
  • people are not paying for what they're using. Absurd
  • features are stuck behind the telemetry check
  • Telemetry having impact on caching is crazy.
  • Telemetry-off meant stale auth/context every 5 minutes; cached agents silently degrade fast.
  • The shadiness with all this A/B testing of core functionality is kinda disrespectful to us.
