The primary business and concern of the CRAs is their business clientele, and their reporting to the CRAs and their purchase of credit histories of consumers. Consumers are, at best, a secondary factor,.
Credit history on an account that has been closed for more than 7 years will have most of their prior derogs excluded under requirements of the FCRA, and normally will have all derogs removed after 10 years. Thus, they are incomplete account histories for use in determining a consumer's prior payment history, and creditors gain little or nothing in continued reporting of such accounts.
Yes, deletion by the CRAs impacts the consumer's length of credit history scoring, but the advantages to the CRA in clearing out incomplete dead wood is a more important consideration for them.
