Not all data brokers are sketchy, some are very good. Data brokers help assess who is creditworthy and lowers rates for more trustworthy people, and allow the creation of more specialty lending products.
Credit checks, and the 3 big companies that do it, are already pretty regulated. I don't think they're counted as data brokers that'll have to comply with Delete Act. Can anyone confirm?
update: Looked it up and this seems right. The credit bureaus have specific exemptions in the Delete Act, specifically because they're already covered by the "Fair Credit Reporting Act". But it does apply to adjacent "people search" features from the same credit bureaus.
Also you can't delete your own credit history data unless it's proved inaccurate. Though you can't delete freeze it.
