To be clear: the impression I got from the video was that this was a charity that the provider was offering, not that they were using Experian to validate eligibility for other charities.
The revenue for their charity is most likely dependent on government subsidies that are contingent on the financial status of the patients they're helping.
Even though they're determining eligibility for "their own" charity, they're likely determining eligibility for "other charities", if you follow the money.
I don't know what this has to do with my point; you can do this "follow the money" analysis to take any argument anywhere. On message boards, at least, it seems to turn out that it's almost never a good idea to just "follow the money".
