The .org top-level domain is controlled by the Public Interest Registry (PIR), a non-profit organisation. The Public Interest Registry is itself a subsidiary of the Internet Society (ISOC), another non-profit organisation.
The Internet Society has plans to sell the Public Interest Registry — and the .org domain with it — to a company called Ethos Capital, which nobody knows much about. Ethos plan to buy the PIR for $1.1 billion via a leveraged buyout using the PIR's assets as part of its leverage, which would meant the PIR would end up with a $300m debt as a result.
This all has to be approved by the Internet Corporation for Assigned Names and Numbers (ICANN) who oversee the domain name system for the entire internet.
ICANN seemed inclined to grant approval but they've met with some bitter opposition to the transaction, including from California Attorney General Xavier Becerra. This is significant because ICANN is incorporated in California and Becerra is therefore responsible for making sure ICANN lives up to its articles of incorporation, one of which states it operates for the benefit of the Internet community as a whole.
Several former ICANN officials are involved in the Ethos Capital transaction, which stinks mightily.
There are 10m+ .org registrations and the worry for users is that the price of domains could be increased if the deal where to complete. Ethos Capital are definitely not non-profit and they could significantly increase prices to take advantage of those who want to hang on to their established .org domains.
