I think that web site is out of date. I clicked on a few, and the companies are still hiring Colorado people.
For example, clicking through the Accenture link to a job listing shows:
"As required by Colorado law under the Equal Pay for Equal Work Act, Accenture provides a reasonable range of compensation for roles that may be hired in Colorado. Actual compensation is influenced by a wide array of factors including but not limited to skill set, level of experience, and specific office location. For the state of Colorado only, the range of starting pay for this role is $112,000-$134,000 and information on benefits offered is here."
