No marketing or design company would duplicate a band from another experiment (taking care to rotate it to make it look different nonetheless). Even in that unlikely scenario, Thermo Fisher is still responsible for the scientific data they publish.

In some of the experiments, the same random noise background exists with different black blobs superimposed at where you expect the correct value to be. Ie they took a fixed realistic-ish looking background, and drew in the 'correct' values

Its hard to argue that that isn't fraud as a result. It isn't touching up existing data, its fully fabricating data

The background painting could maybe be explained like this (depending on what was hidden), but I don't think the duplicated blobs have a good explanation, especially because some were rotated to try to hide the manipulation.

I disagree. If you look at the photos the painting used to make black blobs shorter. As I understand, black blob vertical position is the weight of a molecule, and they want to hide the fact that there are heavier or lighter molecules. So originally there was a long blob, and they made it look shorter.
