There was a time when vi and some of its variants (for instance vim) were considered relatively heavy, at least on shared servers. I'm thinking back to my Uni days with two rooms full of vt100 clones all connected to one poor box and people telnet-ing in from other locations too (SSH was pretty much brand new at that point so wasn't available). Of course emacs was worse, but there were even leaner options than vi/vim/related too.
