As far as I understand, at that time the science did not suggest that this was the best path - at the time the science was inconclusive with reasonable support for both aerosol and droplet options; and the blocked videos had just as much, just as good scientific basis as the official position. They were blocked purely because of the WHO political decision to promote one option over the other, and that WHO decision did not have a proper scientific backing - and when that was challenged in public, the response was to block the scientific arguments which were valid and reasonable already at the time, and some time later turned out to be conclusive. Furthermore, there was a long gap of many, many months between a scientific consensus that the WHO position was literally wrong and the changing of that position - and during that gap any blocking of these videos was not only without a scientific basis but even directly going against what science suggests.
