Open APIs and third-party clients are paramount to enabling privacy-friendly access to otherwise proprietary silos on the web. Through the use of those APIs and clients, it was possible to interact with Reddit in an entirely user-controlled, privacy-friendly way. Reddit’s restrictions take that choice away, making their official app virtually the only portal to the information on their platform available to mobile users.
I hope that these communities stay private until Reddit actually responds properly to this situation. Call me cynical but I don’t think they are going to back down on their decision, they stand to gain too much and I bet people will forget about this in a month or two
