Because clients connected to a "hidden" SSID broadcast -in cleartext- that AP's SSID in many frames that they and the AP transmit as a normal part of operation, [0] deactivating SSID broadcasts gains you no security, a fair bit of inconvenience, and -potentially- reduced battery life when you move out of range of the AP as the client spams "are you here?" messages, rather than taking the absence of SSID broadcasts as a sign that it's out of range of the AP.

Now, you could "hide" your SSID to reduce the number of SSIDs that appear in a WiFi network browser in a congested area... but that's a thing that -IMO- doesn't get you much for the hassle.

For security, either use WPA2-Personal in AES/CCMP-only mode with a long, randomly-generated password, or WPA2-Enterprise [1] in the same mode.
