The FBI sleeps when libraries burn
90 days is just the standard timeframe for responsible disclosure. And normally that’s just a baseline with additional time being given if there’s genuine communication going on and signs they’re addressing the problem.
90 days is standard for “you’re code is fucked when someone presses this…”; if the issue is Dave left the keys in the parking lot and someone copied them, two weeks is more than enough time for them to recieve the notice, create a ticket to rotate the keys and a ticket to trigger an investigation (gotta document anytime an org fucks up so it doesn’t happen again, right?). Maybe I’m over simplifying it though, I don’t know how their org operates.
