The number of people who are marginalised is... marginal. By definition it doesn't have a sensible impact on profit. That's precisely why it is a problem to be marginalised.
Even literal regulated electricity utilities aren’t expected to provide service to every last marginal customer.
For example, a poor old grandma missing many electricity bill payments usually will see leniency if she is polite, the utility eventually won’t try to collect cash anymore and instead put a lien on the home while continuing to provide service.
But if the billing department receives multiple threats from her, then they may just cut the service.
Isn’t that… life?
