APE: Activist /​ Altruistic Private Equity

Has there been much discussion around the role of private equity as a tool for directly intervening in a cause area?

This example came to mind while going back to Lewis Bollard’s first appearance on 80k Hours:

Instead of trying to infiltrate workers into a factory farm or slaughterhouse, why not buy the entire operation and have unlimited access to documenting its practices? There could be a livestream, interviews with workers about their working and living conditions, public tours for the media, students, public officials, etc.

Based on the Leah Garcés episode, it seems like there are many chicken farmers who would be happy to sell their business. I’m guessing one could be purchased for a few hundred thousand to at most a couple of million USD, depending on size/​quality. Slaughterhouses are presumably more expensive, but they may have the advantage of being closer to medium-sized cities, with greater opportunity for collaborating with schools and businesses to organize tours.

A second phase of the intervention would be improving the animal welfare standards at the facility, with an aim to raising industry standards more generally, and eventually selling the business.
