Wireless Disbaled in Motorola SBG6580 - Time Warner Internet

This question is about "Wireless Disbaled in Motorola SBG6580", with Time Warner Cable internet and apps. I saw a forum about this issue and cannot reply to it. I subscribed to Spectrum a week ago, have this model as my own modem...and the wifi is intentionally disabled by Spectrum. Why do you disable the wifi, and what is the point of "allowing" customers to use their own equipment? It is frustrating and causes unnessary expense in purchasing extra equipment (i.e. router).
