In their political minds it's probably all acceptable as long as it opens before the olympics. Who cares about the people who actually need to make use of it frequently.
I get annoyed about the LAXit situation but the people I think losing out the most are the airport workers trying to get to public transit. I have tried using public transit on arrival a few times and it's sad that the worst / most frustrating part of the trip is waiting for the slow, infrequent, poorly-dispatched shuttle bus to the bus center or aviation station.
That said, LAWA really better open it by early 2027. Else watch the olympics be during a big heatwave which reveals some issue with the tracks or signaling system causing an epic breakdown
