The trouble, as laid out in a recent SF Standard investigation and amplified in a wave of online commentary from former employees and longtime visitors, centers on the tenure of CEO Scott Sampson: years of declining donor confidence, significant staff reductions, and — according to the reporting — personal expenditures that are now drawing scrutiny. New gifts to the Academy's endowment reportedly averaged less than $500,000 per year under Sampson's watch, down roughly 90 percent from the six-year average before he arrived. That's not a rounding error; that's a signal that major donors, the kind whose names go on planetarium walls, were watching and deciding to sit this one out.

For a place that charges what it charges — the ticket price regularly comes up in conversations about where the institution is heading — the math only works if the experience justifies it. Several visitors and former staff members have said the same thing in different ways: the public floor exists to fund research and collections, and the collections and research are supposed to make the public floor worth returning to. When that loop weakens, everything weakens.
