They just refunded pro rata if you wanted out from the annual contract which they'd changed the terms on drastically, presumably OpenAI will offer the same to existing subscribers.
A shame that Tibo feels the need to BS like this. I predict another "we heard you...we handled comms badly...here's some resets" style post in a few days.
