Also consider that Fable launched on June 9. Many people including myself bought a 1-month Anthropic subscription just to use Fable.
By extending it to July 12, they're gonna get a second month out of a lot of such people. If it really expired today, I wasn't going to renew my month.
I immediately downgraded my subscription as soon as they revoked access, then upgraded it again once Fable came back. So they're getting no extra month out of me unless they keep Fable available.
My theory is they saw capacity would have issues during weekday working hours due to last minute frenzy of usage, so would rather it happen on a weekend if it has to happen.
