I like how they phrase this like it's a considerate product decision, while it's essentially them not wanting to shoulder the expense of storage. Without knowing more about their product internals an immediately obvious and important feature getting the axe from this is highlights. Example: I will stream and then go back the next day and cut the video down and take the snippets and post them to youtube. These highlights then lead to interest in the channel which leads to more viewers. Now I need to archive all my stuff locally, and upload it over my mediocre connection. If they limited the archival time window to 4 hours after the end of the broadcast they would have their drastic reduction in infrastructure cost while not totally removing a valid and arguably important feature.
