Yeah, that’s an incredibly short timeframe, done on a Friday with what looks like an 8-hour time difference.
Back before bug bounties, the industry mostly coalesced around RFPolicy[0] in terms of security notification and response timelines. Upon establishing initial contact, five business days were given for a response before public disclosure if no response was received.
To me five business days seems appropriate if you’re acting in good faith and truly interested in hearing a response. It doesn’t feel like that was the intent; it feels more like a weak attempt to use the lack of response to pile on further.
