With what intention? Honest question, I don't see a strategic advantage in posting this on a Friday. More of a disadvantage, actually, with less visibility.
The point is less visibility/criticism. Since this is confirming pretty bad news (the attackers had access to the environment variables.) The concept of a Friday night news dump is a fairly well-worn, but basically true, trope.

The intention presumably is to be able to say they communicated this while (intentionally) limiting the amount of awareness that's spread about this.
