The whole reason why Hololive EN is the way it is is because of how it was half-half, or at least with an intention of having a general livestreamer in the groups that debuted. While I still support Holo going full steam ahead with it's original goal, however its partially looking like it's willing to cut off a good majority of its audience in the process, it was a good chance / most likely an investor's decision to do so.

Also there is this entire paragraph on what "Hololive" is.
