Society is governed by information. Whoever has the information succeeds. Whatever the field, whether it be economic competition, nuclear and physics research, or agricultural activity, information is fundamental.
Because it is such a valuable resource, in many cases it is hidden and kept secret to gain advantages.
However, from the perspective of the Torah, the opposite is true. Information is meant to be shared. More precisely, Torah information is meant to be disseminated. It makes no sense for a teacher to withhold their teachings regarding the observance of a particular mitzvah if doing so will prevent people from knowing how to fulfill that mitzvah.
Furthermore, the laws of Shabbat include the idea that a rabbi has an obligation to make it clear to his community that Shabbat may be disregarded in cases of life-threatening danger. We see that the Torah, so to speak, compels the sharing of information.
Even the wisdom of Kabbalah, which for many years remained hidden and was only taught in small groups and to specific people, after the teachings of the AriZal, Rabbi Yitzchak Luria (Tzfat 1534-1572) began to spread and reveal itself to the whole world, particularly since the emergence of the Hasidic Movement, at the hand of Rabbi Israel Baal Shem Tov (1698-1760).
