You're asking me if it compromises cybersecurity. I know I wear a navy uniform, but I must say I haven't worked within the navy structure for a number of years, so I'm not aware of their analysis of the threat that this morale tool introduces. I wouldn't want to speak out of turn.
The navy has done an analysis of what Wi-Fi means to the security of their platforms and the morale advantage that it provides to people who will deploy for months on end through having access to communications with families back home and what that provides for them. In terms of a threat or a cyber-threat, I'm not aware of any because I'm not working in the navy lines.
