>>38101171 said, she was busy with non-VTuber stuff at the time, but there were also some tweets that hinted at the company trying to replace her, who knows. Viewers got mad, and also confused (many couldn't actually tell their voices apart).
After half a year or so, the OG Ai gradually returned, the company released a statement on twitter along the lines of "we heard your feedback and will make them easier to distinguish" and they gave the clones different hairclips. Later on they also gave them their own models and channel. But the damage was done, a lot of viewers had left for good and then kept spreading false info (some still do this today). She even made a video at one point to address this (

Her popularity never recovered and her channel pretty much stopped growing. So about 9 months ago she streamed one last big concert and then went on indefinite hiatus.
