This is an artistic project to make a fun and artsy poster, so it's not at all "suspicious" that the map projection is not critical to the artwork.

It also appears to be open source, so perhaps you can open a pull request with your improvements based on your cartographical experience.

You are absolutely correct. Suspicious was the wrong word and I did not mean to criticize the author or the work.
