Class action is probably their best bet. Up until now, for the most part, companies have opted to refund digital purchases like this, like when Google ended Stadia and refunded everything. And while it's easy to laugh at people who trusted and believed that they had permanent ownership, I truly hope that there are enough people who stand up and take this to court, because people shouldn't be punished for not being cynical like us. And if a company is going to sell something as a purchase, rather than a rental, they should at least have to continue to provide it to those who did buy it. I have several games on Steam that can no longer be sold due to licensing reasons, but Valve still lets me download and play them, because I purchased a license. Sony and Discovery should either have to refund people, or continue hosting the files for those who purchased these shows.
