Why would it be available for only short periods? Eagle is a HEO.

I said RELATIVELY short periods... what is the maximum time that the proposed data transponder will be available to a given ground station, with favorable squint angles, on any given orbit? What is the TOTAL, cumulative access time per day? From the perspective of an emergency manager or disaster team captain, it is certain to seem small when 24/7 service is available from other sources, particularly sources that they have already invested in. And since the design team is looking into their crystal ball at what the state of things will be 5 years down the road at launch, surely they have seen that the entire internet access landscape is sure to have undergone a sea change by then? (Bill Gates sure seems certain of that...)
I repeat: if the design team has anything from the NGOs to bolster the claim that they (NGOs) "need it for emergency data communications", then let's see it.
