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.

There's a particular frustration among people who worked on the museum's more ambitious projects — the Morrison Planetarium shows that screened internationally, the productions that required filming in Chile, the computer graphics work that took real scientific ideas and made them navigable for a general audience — that this kind of output might now be harder to sustain or could be replaced by cheaper alternatives.

The Academy has not made a major public statement about the leadership situation as of this writing. What visitors will notice, if they walk through this week, is what they don't notice: the same exhibits, the same entry fee, the same line at the café. The changes are in the ledger, not yet on the floor.
