To be fair, they didn’t say that they needed more resources for remote streaming

If your goal is truly to benefit the public, why wouldn’t you start a non-profit?

Because your non-profit isn’t likely to go anywhere; Capitalists don’t give significant money to non-profits, but they’ll invest in a public benefit corporation because of the potential for profit. The corporation can then take their money and use it for whatever public benefit it intends to work towards. It’s a workaround to try and scrape some benefit to society out of capital, that otherwise wouldn’t exist.

Whether Bluesky is actually a good example of a public benefit corporation or not, I have no idea, I don’t use it.
