They are attributing it to a pattern of claims and declarations regarding one's own beliefs and desires that so-called progressives in places like SF and Berkeley make, which directly contradict their behaviors.

Here's a great example: https://www.johnlocke.org/good-for-thee-not-for-me-robert-re...

"Robert Reich, a left-wing professor at the University of California Berkeley who served as labor secretary during the Clinton administration, is very concerned about income inequality. He urged Wall Street executives to “invest” in cities by funding low-income housing projects. He also praised a “promising initiative” to promote the construction of affordable housing units in San Francisco.

Reich is not so keen, however, on a proposal to tear down a dilapidated building in his Berkeley neighborhood and replace it with a 10-unit development that would include low-income housing.

Reich and some of his wealthy neighbors are imploring the city’s Landmarks Preservation Commission to designate the dilapidated structure, known as the Payson House, as a Berkeley landmark in order to stop the proposed development. In a letter to the commission, Reich said the proposed housing units would destroy the “charm of an older era of Berkeley” and likened the developers’ actions to “the illegal practices and corrupt politics of the late nineteenth century.”
