The current crop of LLM-backed chatbots do have a bit of that “old, good internet” flavor. A mostly unspoiled frontier where things are changing rapidly, potential seems unbounded, the people molding the actual tech and discussing it are enthusiasts with a sort of sorcerer’s apprentice vibe. Not sure how long it can persist, since I’ve seen this story before and we all understand the incentive structures at play. Does anyone know how if there are precedents for PBCs or B-Corp type businesses to be held accountable for betraying their stated values? Or is it just window dressing with no legal clout? Can they change to a standard corporation on a whim and ditch the non-shareholder maximization goals?

No, they don't. They soak up tons of your most personal and sensitive information like a sponge, and you don't know what's done with it. In the "good old Internet", that did not happen. Also in the good old Internet, it wasn't the masses all dependent on a few central mega-corporations shaping the interaction, but a many-to-many affair, with people and organizations of different sizes running the sites where interaction took place.

Ok, I know I'm describing the past with rosy glasses. After all, the Internet started as a DARPA project. But still, current reality is itself rather dystopic in many ways.
