Some cheaper brands, which are subsidized via ads, actively search for unsecured networks. Disabling the Wi-Fi as completely as possible might be worth the time, if you have such a model.

If it's aggressive enough might have to damage what it uses for an antenna

I don't even think it's limited to the cheaper brands. I thought I heard about Samsung (or some other similarly large vendor) TVs connecting to networks their servers knew about for updates and stuff all of course without your interaction/consent. I might have just read that as a possible future thing though it was a while back that I saw it.
