the issue stems from a distinction between tlv record "lightning comments" which are very limited and hacky direct messages to podcasts (like youtube superchats) and the general comment system based on activity pub (mastadon-like). fountain is moving forward with lightning based comments while other platforms are looking for a more general commenting system separate from lightning payments.

it is all the usual "cordial" fighting that occurs with any protocol development while trying to solve a real problem of decentralized commenting and paid messages.
