There is certainly a conversation to be had regarding consumer protection laws, the nature of an appliance, and the trade-offs thereof but this is not that conversation and I don't think you engaged in good faith with the comment you replied to.
Read it again: "LG Electronics is working with developers to remove the residential proxy option from their apps on the webOS platform"
It is working with developers it has a contractual relationship with, and has approved their apps for download from its "app store" -- this one: https://gb.lgappstv.com/main/tvapp
...where 42% seem to be ADDING THE TV TO A BOTNET.
LG TVs form a substantial botnet, and LG didn't appear to know or care.
This is not about a person using their own TV to add it to a botnet (WHY WOULD THEY DO THAT?), it's about "app developers" knowing that LG is lax in checking what "apps" do, and putting out trojan horse apps that, if the TV user installs them, adds the TV to a botnet, without the TV owner's knowledge.
This is entirely orthogonal to "can I run my own choice of software on my LG TV?", which is not addressed in the article at all.
