There are two ways that the early deadline for "early bird" helps us: 1. Some people will not decide whether to come early enough to get the 7-week-out rate, and they will therefore pay more. For those people, the change in policy is effectively a rate increase, and it will increase our revenues. 2. Some people will want the early rate, and will register early and pay for that. That increases our early estimates about registration revenues, and allows us to make early determinations about expenses we might need to adjust in order to make meetings break even. As we noted both before and during IETF 101, meeting registration revenues are down. They've also become somewhat unpredictable, with meeting revenues varying from historical trends and payment dates also varying. We have lots of possible explanations for this, but nothing that is definitive. Speaking personally (i.e. I don't know whether this influenced other IAOC members), one appealing feature of the new deadlines is the way it aligns the signals of registration and payment; our old approach tended not to encourage early payment, and the proposal we are making has an incentive for that (and compensates the IETF with more revenue when that signal is not present). It could well be that meeting revenues are on a permanent downward trend, but if so that will also affect the size of the meeting we need to support and consequently will change our forecasts. Good forecasting is super important when we are aiming to sign contracts with hotels a long time in advance of the meetings we plan to hold. A more accurate forecast of lower revenue is, for these purposes, as good as an increase in revenue. I hope that makes things a little clearer. As I said, I don't want to speak for all IAOC members in representing their reasoning for supporting this, but I think the theme above was one of the prominent parts of the discussion and was important to me.
