How the hell did they manage to screw this up?! I remember a "Trajectory nominal" callout at some point...

It looks like the ascent was ok. The trouble was in the second burn, which might have not happened at all.

Looking at the groundtrack graphic that BO published, which yes, could be just PR and not truly representative, the initial orbit does seem to be at 30 some degrees, which matches the TLE from that initial orbit. SECO-1 was announced on time, so that first burn probably was ok. Except for the higher apogee, compared with what was published pre-flight, I'd say that initial orbit is ok.
The plane change is a tradeoff: you could launch right into that target inclination, but in this case the ascent would have to be north-bound, with barge likely in not-so-calm seas. If they have performance, why not use it and make the plane change at apogee? That pre-flight groundtrack puts the second burn near the equator, so this fits with the little that we know.
Just checked the man himself before posting, and there are fresh news:

I wonder if there are pictures of the payload?

Now that we have a more complete view, we wanted to provide an update on our NG-3 mission. While we are pleased with the nominal booster recovery, we clearly didn't deliver the mission our customer wanted, and our team expects. Early data suggest that on our second GS2 burn, one of the BE-3U engines didn’t produce sufficient thrust to reach our target orbit. Blue Origin is leading the anomaly investigation with FAA oversight to learn from the data and implement the improvements needed to quickly return to flight operations. We have been in steady communication with the team at AST SpaceMobile, we appreciate their partnership, and we’re looking forward to many flights together.

I guess everything worked... except dropping off the payload at the correct orbit.
Cool video of New Glenn’s fairing re-entry. For this flight we installed an exo-atmospheric reaction control system (RCS) in the fairing to control re-entry and enable recovery of the fairing. We’re planning a parachute recovery later this year, and the data from these fairings gives us the learnings needed to develop and refine that capability.
