That quote is taken quite out of context, reading the discussion linked it is clear that this comment in particular is about the people of the Nim community who split out and created the Nimskull fork. And please let us keep on topic here and discuss choosenim.
That being said Dominik has left the Nim community, so `choosenim` is currently in an awkward state without a maintainer. I'd love to see the project continued, preferably of course as an official project, as it is in my opinion the superior way to install and manage Nim.
