Microsoft Copilot terms of service have been updated to include this gem: "Copilot is for entertainment purposes only." https://www.theregister.com/2026/04/02/copilot_terms_of_service/
@jt_rebelo @GossiTheDog Strictly speaking that's the ToS for the 'consumer' version; so it's even more expansive in its data collection; but I don't think that MS actually has anything better for Fancy Enterprise Copilot 365 (E5); except possibly more aggressive 'burn more tokens if the first time seemed too nonsensical' defaults.
At least the consumer ToS assures us that "you may stop using copilot at any time" your average Azure tenant sure doesn't make it seem that way.
