Remember when LG Smart TVs phoned home with USB file-names...?
After being found out, the first thing LG did was claim that the webpage was invalid.
But sysadmins pointed out that every URL was likely logged by LG Server's anyway.
Along of course with everyone's USB file-names supplied via URL parameter etc.
================================
So I agree the best option is to avoid Smart, as most people don't even really need it.
But the bitter pill is, unlike Samsung, LG still actually sell a range of non-smart TV's...
Whereas Samsung stubbornly wants in on the Facebook / Google Ad-slinging game...
