I make no comment about the content of the video linked in GGP's post.
That being said, the following is publicly known (but unverified by me) and quite apt to affect impartiality (whether under his control or not, whether consciously or not):
1. He was persecuted in China by the authorities and barely escaped with the posessions on his body.
2. He is currently under attack by brigades and agents of the persons he is critical of. The attacks follow standard psychological warfare patterns, including death threats to himself and the family.
Additionally, some speculation from me:
3. He has no journalistic training, both his business partner and his peers in the wider YT/Patreon business don't have either, and to me it seems both content producer and audience have come to a shared understanding that the shows are primarily entertainment and should not be held to the same rigour of journalistic integrity one would expect from e.g. a traditional print periodical. Adv Media's income entirely depends on YT/Patreon, and employing sensationalism – which results in uneven amplification of the reported reality – brings in more money. I haven't seen a completely sober/dry video.
Their experiences living in China line up with mine. I haven't seen an instance of them compromising their integrity.
