>>32030775JP market are losers who want to RP date an egirl. Granted half of the girls don't even do GFE, they also still don't do much male collabs or make it a big deal. JP vtubing is essentially a service; an interactive show. Even the least GFE JP chuba knows their audience are simps and will do some fan service every so often, but ultimately the community likes simply "hanging out" with a cute girl and listening to her talk and play games. There's also the idol aspect, which ultimately leads to the gachikoi wanting their favorite chuba to succeed, not necessarily out of some weird romantic obsession but because they adore her. At the end of the day however, the chuba is playing a character more than a real person, and the VA fucks off and does their normal life.
EN market on the other hand are half losers half normies. Normies just see chubas as streamers with a mask, but losers are weebs who want EN chubas to be just like the "submissive" Japanese idol chubas they don't understand. Unfortunately for the losers, streaming is very popular among normies in the west. Losers are also sex starved weebs who lack the average Japanese male beta characteristics, and tend to cry when things don't go their way. So when a loser cries about male collabs, the western chuba is confused, because the western normie audience and culture has no concept of such a thing. They too want to "hang out" with a cute girl talking and playing games, but that idol aspect is non existant and GFE isn't much of a thing when western simps can just get borderline full service from vshojo. So there is no "muh purity" because there's no idol culture. Thus the normie fans that vastly outnumber the losers insult them for demanding no males because in the west that's just straight up cringe. Normies will also take note that most western chubas aren't really much of a character. Western chubas are really just any twitch girl with an anime mask. Which is true when you consider most JP talent have been actors and entertainers who put on a show with bs emotions and reactions for audiences, while most of EN have just been dime a dozen shit posters and streamers.
tl;dr: culture shock and weeaboos
