Not to mention that nobody claimed that EMC was the only supplier for 98% of the market. As a similar claim, RedHat[1] state that 100% of Fortune 500 banks, airlines, telcos and healthcare companies rely on RedHat. Is it a correct statement? Probably. But does it mean that RedHat exclusively sells to 100% of those markets? Of course not.
