Yeah, it's not an accurate indicator since various factors play into how many stars Neovim has, e.g. Vim is prebuilt into most OS distros, so lack of a need to download it, Neovim is more contributor friendly, etc. I highlighted this not to show the insignificance of Vim, but rather the rise of Neovim.
NeoVim certainly got a lot of press for a while. I think it has faded quite a bit in the past few years since Bram stole their thunder somewhat by integrating their biggest selling points.
I am fairly certain I have NeoVim starred on Github. I haven't used the editor except for an hour to try it out when it was new. I use Vim all day every day for work.
I would expect a similar situation for many of those stars.
