Given that Bluesky is VC funded, I imagine it'll just be a matter of time until the monetization, ads, and growth hacking start. Enjoy it while you can, I suppose.
AFAIK all the "public benefit" aspect does is remove the ability for investors to sue the company for failing to maximize shareholder value. Given sufficient share ownership, it's still possible for VCs to force Bluesky to do whatever they want.
