So he took a single case where pie chart has been used wrongly and from that extrapolated we shouldn't be using pie charts?
Seriously... either explain your logic with supports or don't bother writing such misleading pieces of text.

- they fail to convey information because people have a really hard time judging relative areas instead of lengths.
- there are times when a pie chart is appropriate
- once you get data that isn't widely different or you have lots of categories your pie chart would be better as either a bar chart, or as simply a data table
- pic of horrid "word features" chart
- why is it bad?
- releases occur chronologically, but the data is displayed in a clockwise fashion with no obvious starting point
- the pie chart has no values on it at all, so we are left staring at the chart trying to guess the relative sizes of the slices
- the chart is 3D
- which makes it extra bad for estimating relative sizes
- 3D pie charts are simply an abomination
- making them 3D just makes them even harder to interpret
If you wanted to make a chart that looked impressive but contained as little information as possible, you'd have to work to do better than the pie chart.
