OpenTable sounds like it would be open-source, but it appears that it isn't
I think the parent comment to yours made a sarcastic take using a variation of the popular ambiguity Free as in Beer [1] that usually differentiates between free as 0 cost and free as freedom as a reaction to the OpenTable software being free to use rather than open-source
You go into a bar, you order the IPA you liked someplace else, you see they've got a heap of cans... the bartender reaches under the bar and hands you... an open can.
No right? You don't want that one. Why the hell is it open?
What does this mean?
