An undisclosed Microsoft presentation is now central to a multi-million dollar antitrust fight
Microsoft faces a £270M antitrust case over licensing practices. A damning internal presentation just surfaced — and enterprise CIOs who surrendered perpetual licenses may have a claim.

Why it matters
This UK antitrust case signals that regulators are treating software licensing restrictions as anticompetitive lock-in tactics. For practitioners, it means re-evaluating cloud commitments made under pressure and understanding the legal validity of secondary-market licenses — with potential leverage in contract renewals.
The key facts
15 to knowValueLicensing lawsuit: £270 million (~$361M) alleging Microsoft incentivized customers to abandon pre-owned license resales for subscriptions
Internal 'Second-Hand Software' (SHS) presentation labeled 'known adverse document' — content undisclosed; disclosure deadline October 31, 2026
11 previously confidential documents now unsealed; search warrant on emails of former COO Kevin Turner, ex-president Jean-Philippe Courtois, and VP Joe Matz (July 2012–June 2020)
Parallel opt-out class action filed May 2025 by UK barrister Alexander Wolfson alleging overcharging of public and private organizations over 10-year period
Microsoft's defense: contractual restrictions 'objectively justified' and 'necessary and reasonable'; benefits 'outweigh anticompetitive effects'
Forrester analyst: case signals 'inflection point in European tech litigation' — software licensing mechanics now examined as lock-in tools
Practical implication: enterprises that surrendered perpetual licenses or accepted resale restrictions may have forfeited quantifiable asset value; secondary market for perpetual licenses remains legally valid
