They want to add some optional subscriptions in near future (a la Discord), and more long term they want to have some way of creators earning money from their followers and Bluesky getting a commission from that.

I wish there wasn't a need for a business-model to begin with for social media. Honestly, being business-driven is what turns them all to shit, as far as I'm concerned.

That being said, the lights need to be kept on somehow... some model similar to what Signal or wikipedia does might be a solution. Content-moderation is probably the big challenge though that they do not have to deal with to the same extent, so not quite sure how that could fly either...
