Why choose Public Benefit Corporation (PBC) status with the extra compliance burden? (e.g., Coursera)

I'm trying to understand Public Benefit Corporations (PBCs) vs. traditional C-corps, and I'm still not seeing the appeal despite the explanations.

From what I understand:
- Formation/ongoing fees are the same
- You add extra duties to consider public benefits/stakeholders
- Extra annual "benefit reports" or impact disclosures
- No tax breaks or cost savings

So why do founders/companies like Coursera choose this? Is it legal protection against activist shareholders pushing pure profit? Or does it actually help with fundraising/valuations long-term?

Any positive or negative stories of a PBCs to read?
