The original vi has not been maintained for many years. Most distributions, including Debian, Fedora, etc, use a version of Vim which (mostly) is similar to how Vi was.
From Fedoras wiki:
"On Fedora, Vim (specifically the vim-minimal package) is also used to provide /bin/vi. This vi command provides no syntax highlighting for opened files, by default, just like the original vi editor. The vim-minimal package comes pre-installed on Fedora."
From the vim-tiny package description on Debian:
"This package contains a minimal version of Vim compiled with no GUI and a small subset of features. This package's sole purpose is to provide the vi binary for base installations."
