The pedantry was intended to point out that there is plenty of room for publishers to mislead when they don't detail how the data is collected. When you don't have access to the data, it is usually the best one can do. Even the comment by Kristen McLean has limits, though they are much more forthcoming about what the data includes. That said, I think they summed it up best when they said publishing is a gambler's game. That being said, whether the outcome is good or bad for a gambler depends upon how much they invested and the return across all of those bets. Their data does not venture into financial aspects. At best, it gives us an idea of the minimum number of units sold in a particular subset of the market.
