One issue is that the main info browser is in Emacs, so if you're not an Emacs user, Info pages aren't that accessible. There is a standalone info browser but it's not as nice as the Emacs one. And there are html converters but those are even worse. Back in the day, I doubt that it occurred to anyone that a lot of GNU users might someday not use Emacs. I do constantly use the Info documentation for Org-mode and a few other things, but it is observable (and annoying) that some large GNU programs like bash are documented only as man pages afaict.
