One of the fundamental tenets of roleplaying games is to give your players the ability to make meaningful choices. If the players don't get the opportunity to make decisions about what they are doing, you head down the path of railroading. It can be easier controlling an adventure this way, but it can end up being very unsatisfying for the players, who can start to feel that nothing they do makes any difference.

Giving players choices can be more difficult, but ultimately much more rewarding for everyone's gaming experience.

This applies to the GM running the game. Nothing says that the players have to give each other all the available information and choices.
