The significance of this ruling goes beyond the internet - it reveals the fundamentally reactionary nature of the US legal system and the judiciary which has the power to overrule government agencies if they decide to encroach on the turf of big business. In that light, all the leftie kvetching about Obama's "betrayal" is a bunch of crock - based in a delusional view of the US polity and the supine position of government in it. The US is a plutocracy, not a monarchy. The POTUS and the USG are strong only if they march to the drum beat of business interest, but they are emasculated as soon as they attempt to march to a different beat.
In that light, any reform is doomed from the start, because if it "moves too far to the left" (i.e. encroaches of the interests of the business owners of this country) it will be surely overruled by the reactionary judiciary. Specifically, the 'Obamacare" was probably stretching the limits of how far the USG is allowed to go before being reigned back by the reactionary court system. Knowing that limits was a sign of political genius rather than a "betrayal" of any kind.
