Did you read past the first paragraph? The linear interpolation applied is so that the tree-ring data better matches the actual temperatures that were collected. The actual temperature measurements still indicate exactly what they indicated before. The question is whether tree ring data is a good way to measure temperature since 1400, or, what happened since about 1960 to cause the model to diverge so drastically. (Or perhaps it is neither and there is some biological factor..) These questions were both brought up as being 'of concern' in the published paper, not hidden away or covered up. Linear interpolation is a purely deterministic process... as such, it could be easily removed from any data that had it applied (which is apparently only the tree-ring data in this case). To compare this to massive bank fraud is nothing short of malicious. Certainly, be upset about the missing data. But be more upset about the people who are blindly ignoring all of the data that still points to global warming and actually believe that something like this would disprove it.
