I think the study is well done and robust, although the range of application of the results is somewhat limited. In particular, the conditions where the experiments were done are very laboratory, in the sense that they are not realistic for situations where deepfakes can be problematic, for example, if you know the person they are imitating.
The conclusions, in this sense, may be a bit exaggerated, but it is also true that they coincide with other alternative and similar studies. It is a very specific study with very specific conditions, which is good because it means that the results are less affected by other factors, for example, previous prejudices or biases as in the case of disinformation studies; but it also means that in other contexts they do not have to be fully applied.
