The larger follower count comes FROM this project. I've seen a lot of people being really excited for this style and hoping their own tech stack comes next.

I don't know what's the name of that style, but it's used a lot in the vtuber community. So much so that searching "vtuber logo" on Google Images will return mostly images that look very similar to those from the repo.
It's just something cute to celebrate tech.
