A good example of what this means in practice is developer awards from Bluesky Social. As I understand it, once Bluesky PBC starts making some profit they are planning to begin placing something akin to bounties on successful app projects within the protocol. I believe Graber called this "Coopetition" at some point, where developers are "competing" within the ecosystem but simultaneously working together to make the protocol's foundation stronger.
This is something that a PBC structure makes immeasurably easier to do. Why? Because the company has more responsibilities than simply returning profit to shareholders. The shareholders can't simply sue the company or oust Graber because of this, since Bluesky Social also has a legal responsibility to "develop and drive large-scale adoption of technologies for open and decentralized public conversation". Please do get read on what it actually means to be a PBC.
