Elizabeth made a smart play when she heavily mentioned and praised Holostars during her very first stream.

Normally, Hololivers keep that kind of stuff locked up or at most limited to replying to important Holostar tweets. They do this because they understand that their majority male fans do not want to see or hear about Holostars. Hiding Holostars gives them a boosted audience but this comes at a cost of being risky. At any moment she could accidentally trigger the unicorns into an antagonistic campaign, losing followers, reputation, exposing herself to internet drama, etc.

By being explicit and upfront about her support for Holostars she doesn't even allow unicorns to set foot in her circle. I would almost suggest that she exaggerated how much she loves Holostars in order to make her point very clear. While this has noticeably hindered her numbers (subscribers, viewers), she has reliable foundation to build a loyal fanbase and she has immense freedom that GFE vtubers can't afford to have. ERB could have a "boyfriend voice on stream" yab and almost nobody would care.

ENReco streaming is giving her fresh exposure. ERB will be the queen of vtubing by 2026.
