It's absolutely a rebuttal. If you're making a statistical/empirical claim, especially one that goes against orthodox economic theory, than robustness to the underlying assumptions is really important.
Subsequently empirical research has found that Piketty's conclusions are extremely sensitive to the way he slices the historical data and the modeling parameters. At best that's evidence of an incompetent econometrician who doesn't understand the tools enough to perform the required robustness checks. At worse, it's evidence of data snooping to shoehorn the the results into a pre-determined hypothesis.
But you don't have to take my word for it. The IMF itself performed an exhaustive robustness check and found that Piketty's conclusions simply don't hold up:
Your link is somebody arguing that perhaps the data doesnt look so bad if you squint at it in the right light.
It's not a refutation. it's not even a rebuttal. It's basically disapproving FUD - "oh well if you pretend the 2008 housing bubble never happened things dont look quite so bad...". Um, ok?
There's even a little plea at the end for the reader to "understand that this is all very complicated and hard to understand". How scientific.
Of course, it is quite complicated sometimes and when he tries to break it down himself he gets himself in knots trying to defend inequality: https://www.nakedcapitalism.com/2012/11/desperate-effort-by-...
