The European Commission finds Microsoft abused a dominant position
On 24 March 2004 the European Commission decided that Microsoft had abused a dominant position by withholding interoperability information and tying Windows Media Player, imposing a record fine. Neighbouring 2001 US settlement is the softer US ending. In the causal graph this event strengthens Antitrust Pressure in Digital Markets, a driver that strengthens Out-of-School Rate, Primary School Age (global) — a worsening welfare path.

On 24 March 2004 the European Commission decided that Microsoft had abused a dominant position by withholding interoperability information and tying Windows Media Player, imposing a record fine. Gates was chairman.
Context
Neighbouring 2001 US settlement is the softer US ending. Neighbouring 2009 browser choice is later EU. He did not sit as the hearing officer.
2001 US settlement is neighbouring. 2009 browser-choice decision is later EU.
Bill Gates was Microsoft CEO until January 2000, chairman until February 2014, then a technical adviser until 2020, and a Gates Foundation co-chair. That is not authorship of every Windows copy, every GAVI dose, or every IRS schedule. Melinda French Gates is a different person. Bill Clinton is PER-000772, a different person. A pledge is not a coverage rate. A docket is not a personality.

What the sources establish
European Commission carries the official instrument or communique. Reuters records the same dated act independently.
Established: 24 March 2004 Commission Microsoft decision, independently reported.
Not established: that Windows share collapsed that week, or a unique later consumer-surplus coefficient from Brussels.
The Commission decided. Courts later largely upheld. US settlement did not bind Brussels.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies The European Commission finds Microsoft abused a dominant position, not a later speech about The European Commission finds Microsoft abused a dominant position.
Co-authors and later implementers named in Context remain on the file. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. The contribution described on this Person row is limited to He was chairman of the addressee. The Commission decided. Courts later largely upheld. US settlement did not bind Brussels. That limit is the alternative to treating office-holding as authorship of every later series.
