I agree that when taken literally, it's a dumb thing to say: literally (i.e., the dictionary definition), the purpose of a system is the reason why it was built, not what it does. But it's a slogan, and slogans don't always make sense taken literally. The point of the slogan is to remind people of the (obvious, I hope) fact that, as I wrote:
> you can't (well, shouldn't) judge something by its intended purpose if what it ends up doing goes against it
If you check my Wikipedia link it shows that the original quote says more or less the same thing: "[this slogan] makes a better starting point in seeking understanding than the familiar attributions of good intention, prejudices about expectations, moral judgement, or sheer ignorance of circumstances".
In other words, it doesn't matter what's the historical context of why corporations were created, what matters is what they do now. You can argue, like it was argued, that corporations as a whole currently are a net benefit. My point is that bringing up the historical context of their original purpose adds nothing to the discussion.
As to your other point, I completely agree that it would be useless to try to defend the Staling regime by pointing out what communism was intended to be. That's more or less the point I was trying to make.
