Excuse the weird link but it seems safe and is just a single long ass image of proofs of Artia's sub riling up ccp shills to support the One China policy and a few other girls showing support of the China antis' spam plans in subtle ways.
Artia has long been posting cryptic comments, and I think various twitter comments and a few reddit comments will shed some light into a shift in perspective for their departure. Unknown if it played a part in the HoloCN being purged, but according to Yagoo's personal post, seemed like the choice was entirely based on profitability and the CN branch being... not at all profitable despite the amount of time they were live.
