Read the actual report, that is not what it says. In fact, the report makes the opposite case for the most part (especially when electronics were also being interfered with and many of them developed holes in their ear drums.) The issue is that bar is so high for proof that the US government, at least publicly, dismissed it possibly to make Americans not freak out. This is all covered in the piece, and it also places people from the GRU at locations where this occurred, and they coincidentally are in a unit that works on microwave length weaponry. Could it be a huge coincidence? Maybe? But I've never heard of anyone developing holes in their ear drums from work stress.
