Why didn't GNU Info succeed man?

As per my knowledge/understanding both help and man came at the same time or have very little time difference between them. Then GNU Info came in and from what I have seen is much more verbose, much more detailed and arguably much better than what man is. Many entries even today in man are cryptic. I have often wondered why Info which is superior to man in many ways didn't succeed man at all. I still see people producing man pages than info pages. Was it due to not helpful tools for info? Something in the licenses of the two? Or some other factor which didn't get info the success it richly deserved? I did see a few questions on unix stackexchange notably https://unix.stackexchange.com/questions/77514/what-is-gnu-info-for and https://unix.stackexchange.com/questions/19451/difference-between-help-info-and-man-command/159817 among others.
