Those people got switched to chrome in the meantime (most of these 2000 era computers are long dead now). Actually replacing these machines with Chromebboks is a often heard advice now.
Since a year or two Firefox was actually good while Chrome stagnated, and use cases for multiple browsers also flourished (ex: keeping a “facebook browser”, or splitting google accounts between browsers). I’d expect heavy computer users to be more sensible to these merits.
