Not that I read the article that was removed, but in this he said he wasn't even that critical himself, just pointing towards all the other critical articles and noting they need to fix whatever is causing them to be written.
This is the actual article: http://archive.is/aCge1 It's mostly fearmongering about 5G affecting people's health which doesn't even seem to be that founded in the one other article he linked to, which contained different fearmongering about the potential health effects of 5G.
