Or it could just be that one of Rev's videos appeared on their homepage. Personally, I feel that Rev falls into the same category as Asmongold. His videos tend to focus on culture war drama to rile up "gamers" against perceived censorship or virtue signalling which cultivates a toxic viewership.
On the topic of the removal of Yostar's decision to remove the skins from Azur Lane's in-game shop, it appears to only impact the English/International servers (Japanese servers are unaffected), and those who already own the skins have nothing to worry about (the files are still in the game). Putting on a tinfoil hat, this is probably the result of a group or individual that holds a grudge against Azur Lane and reported to Google out of spite. The set of removed skins seems incredibly random when considering that there is no disernable pattern between the removed skins (other than being skimpy), and the plethora of other skins in the game which are arguably more questionable and explicit. I'm sure that Yostar has tried to appeal the ruling by Google Play, but they were unsuccessful. Nikke, another mobile game with scantily clad women, has never received any censorship updates so it's safe to assume that this isn't a case of Google Play waging some kind of "social justice crusade."
