This ironically makes them more prone to lying, hypocrisy, drama, and backstabbing than a vtuber who hides behind a mask. Because they only have one chance; once they are irrelevant they cannot catch up. At the same time, they must frantically distance themselves from people and topics which the tide of public opinion turns against, lest it make them persona non grata or taint them as being just another part of the fad, to be forgotten.
The last part is the most crucial aspect. They must constantly take sides. They have presented themselves as people with a human face - a realistic, likeable, and usually, it is implied, genuine - person! - so they will be treated as people. And most of their audience, unconsciously or otherwise, believe that a person should possess enough courage of their own convictions to state their stance on 'important things' - such as the latest e-celeb drama.
Now notice how sensible vtubers can say, "I'm not really allowed/I don't want to talk about this" easily and diffuse shit like that. Because they present themselves as entertainers. At the end of the day, it is easier for them to draw boundaries because they are distanced from their apparent personhood by anime avatars. There is then a tacit understanding among most of their audience that these boundaries shouldn't be crossed.
Many e-celebs have no such outlet because of the way they commonly present themselves - independent leaders of their own cults of personality, where if a company even exists, they control the direction of it - and so they cannot escape public condemnation for inaction or neutrality. In many cases, they have already crossed the Rubicon themselves when they endorsed or condemned something else of a similar nature. So the vast majority of them can be expected to be fair-weather friends who will not only not help you when you're down, but turn around and plunge the dagger deeper, because they have no other choice if they want to survive.
