If you read you'll see the criteria pretty clearly "The 25th Anniversary Hot Rap Songs ranking is based on actual performance on the weekly Hot Rap Songs chart, since the chart’s inception in the March 11, 1989, issue. Rankings are based on an inverse point system, with weeks at No. 1 having the greatest value and weeks at lower positions proportionately less. Due to various changes in chart rules, chart length and methodology throughout the years, songs had varying reigns at No. 1 and on the chart. To ensure equitable representation of the biggest hits from all 25 years, certain time frames were weighted to account for the difference in turnover rates from those periods"
List seems kind of fukked up, surprised no Dre on there, but if it's all objective and based on actual metrics there's no point getting up in arms about it and claiming whitewashing. These are Rap Chart stats, not Rock, Pop or Hot 100, there's a reason Eminem isn't featured on here....
