More recent decisions by ICANN also had a significant bearing on the decision to sell the .org registry. At the end of June this year, in a controversial decision made despite significant and vocal opposition, ICANN decided to lift price caps on .org domains for the next 10 years, paving the way for unlimited price increases on the 10 million .org domain names. That decision massively increased the value of the .org registry from millions to potentially billions of dollars.
