Consider this illustrative situation: A club's fans, an artist's listeners or a creator's followers may be intensely engaged while the relationship belongs to a platform. The next decision is what participation they would value enough to choose directly.
Reach and affection exist, but there is no durable owned relationship or coherent participation model. The visible request may be a book, move, announcement, licence, archive, event or venture. The real question is what becomes harder to reverse once the first commitment is made.
Platform audiences can disappear, and short-term monetisation can weaken the trust that created demand.
