This doesn't really answer the question *, sure clients will have various monetization models (though WTH is transactions). The issue is what is the server/Bluesky PBLLC business model?
Are they going to start putting ads in the feed? Are they going to charge users or clients for access? Stay free and make it up in volume? I have no clue, not sure anyone does either.
