This is not accurate. Piketty has continued to refine the data and add more as it comes available. The main point was that capital flows are interesting and that is beyond contest at this point. The book Capital has some tentative analysis at the end but doesn't make any strong conclusions and avoids taking the focus away from measuring flows of capital. Because it is possible to use this data about capital to come to conclusions that are politically unpopular among some subgroups people have piled on this false critical narrative emphasizing supposed errors and gaps in the data and keeping the focus on some brief remarks at the end of a very large work that has a range of applications. I don't think critics of Piketty did this on purpose. They just pushed unreasonably hard on the data they wanted to find fault with.
