There are some people that asked a similar question but I don’t want who gets raw revenue, but who gets the probably obscene margins (profits thus) from paying $10-20/year for linking a piece of string and an IP address?
$10/year is super expensive for the cost of linking few thousands of requests to an IP address. The point of my question was: who has obscene margins ?
For .org, the non-profit organization that has “obscene” margins is called PIR https://en.wikipedia.org/wiki/Public_Interest_Registry However, they hand over most of their profits after expenses to their parent organization ISOC (Internet Society) which among other things operate IETF, an important internet standards organization.
Of all the top level domains you can complain about, .org is one of the few without a profit motive.
