I pay for Nebula but watch nebula creators on Youtube. Watching on Youtube boosts them in the algorithm and gives them a small share of premium and it is more discoverable. The problem with distributed alternatives is that using them would disadvantage creators on youtube which is their primary outlet. We may need to concede that unlike Reddit or Twitter that clearly can and should be replaced by distributed alternatives, Youtube has proven to be a natural monopoly and as such needs to be regulated to protect consumers and creators from monopolistic abuses.
