>Even in the worst case, if Ethos considers dramatically increasing prices (which, to be clear, we do not expect them to do!), the Registry Agreement for .org requires a 6-month notice period during which domain owners can lock in a 10-year registration at pre-increase rates. This should seriously discourage Ethos from doing this, because it would take 10 years for the new high rate to even take effect for existing registrants, and new registrations would likely fall off right away.
No, the worst case scenario is that they jack up prices and then run a massive campaign FUD campaign about non-profits without .org addresses. Or they start selling of Oxfam.org to competitors. Or hell, they start doing differential pricing, gouging the people they think can pay.
>We're all trying to make the Internet a better place
No we're not. Don't be an idiot. Private equity companies are making money from investments they have no interest in making anything a better place and it's insulting to expect people to believe that.
