“The dissent is unsigned because Roberts wrote it - it was originally to be his majority opinion. When he switched sides, the conservatives left most of it in place and didn’t sign their names to it to give a clue that it was originally his opinion.”

Very fitting that Roberts would write the ruling AND the dissent. Its right in line with “its a tax and not a tax, and, its a law and not a law.”
