Because thankfully,
Sun Microsystems sued Microsoft and won. When everyone else was cowering in fear of Microsoft and abandoning UNIX®️ for Windows™️ NT™️,
Sun Microsystems was the only company who had the gumption to openly oppose the onslaught.
When the United States department of justice sued Microsoft for monopolistic and anticompetitive practices, it could initially find no witnesses, as all the cowardly CEO's were scared to testify against Microsoft for fear of Microsoft revoking their OEM licenses to pre-install Windows on their products; everyone was really scared of angering Bill Gates.
Scott McNealy, bless his heart, was the only CEO with the balls to testify as a witness and it was a crucial, condemning testimony: the department of justice and NetScape Communications Corporation won the day, in large part because of Scott McNealy's bravery to go against Bill Gates and Microsoft.
