Eh, the matter is of such immense public interest and Alito's tone in the draft is so pompous and self-important that it's hard to get upset about the leak, nevermind the millions of women who are going to be affected.
I don't know if SCOTUS should really be entitled to all the secrecy they've been traditionally afforded, since these 9 robes effectively run the country now and have lifetime appointments too.
SCOTUS is overdue for a massive reform, transparency should be only the beginning of it.
