Chase vs. the FICO Score System

Now that JP Morgan Chase has decided it can no longer afford to let consumers continue to have higher credit limits on their credit cards (even if they are very good consumers), Chase has been consistently lowering various consumer credit limits over the past few months.

When Chase was approached and asked about how negatively this will impact consumers that have excellent FICO scores, Chase has taken the position that perhaps it's time that the FICO score calculations should be adjusted. Therefore, I ask you, should FICO scores be adjusted because of a financial institution's poor cash management regarding its lending practices?
