Anyone who owns an LG smart TV must inform all guests and family members that they are being monitored – this is required by LG’s current terms of use. Meanwhile, LG monitors install potential malware and surveillance software on a connected Windows computer.
Not only that but my old LG smart TV (47LM8600, I think manufactured in 2012) has literal suicide timers in its built in apps. Mine has never been connected to any network and yet it mysteriously informed me after approximately three years of ownership that all of its player apps such as Youtube, Hulu, Netflix, etc. would stop working because they were “no longer supported,” all of them within the time frame of the same couple of weeks. It knew this somehow, apparently via magic, or quantum fluctuations, or psychic brain waves. Without internet connectivity.
Obviously I don’t use any of those features so I didn’t give a rat’s ass and I still don’t. But I still find that deeply suspicious.
The only technical explanation that’s not malice would be that some certificate store on the device had expiring certificates and would need an update to continue to function (or rather connect to remote servers).
Are there ever certs that expire in 3 years?
Yes. Certs can expire after whatever time the issuer wants to set for them. That could be six months or 20 years. Some infrastructure has limits on max and min lengths (more max than min usually) but not all and there are best practices as well.
More importantly the certs could have been five years old by the time this person got the TV for a total age of 8 years.
There was some controversy a while ago about Samsung TVs finding and connecting to open WiFi networks autonomously if they weren’t connected to a network explicitly
