Could be, I'm sure other countries will be different since they all have different privacy laws. Honestly though none of this TV stuff really bothers me much in the sense of day to day life, it more just bothers me in the abstract sense.
I don't hook up any of my tv's to the network anyways, and I'm just always on HDMI and a media pc anyways with pi-hole on my router so no ads for me, this was just something I noticed when I hooked up my brother-in-law's tv and he wanted to use the built in smart stuff, which I don't blame him, it's his choice in privacy vs convenience.
