The author of the article is under the mistaken impression that bundling the “smart” features into the TV increases the price. It’s actually the opposite.
By injecting ads and bloatware into the TVs, the manufacturers earn more money, by far, than the cost of the features. A dumb TV would cost more.
The best solution is to decouple them; get the cheapest TV you can with the video quality/size you want, then attach your own device to stream content. I use a modified Fire Stick due to price, mostly with Stremio/Torrentio/Debrid, but there are lots of options.
that works until they start connecting to wifi networks that are open, or to which they somehow got to know the credentials
Fake news, as far as I can tell. Lots of claims this is happening, but nobody has brought receipts. Considering how easy it would be to catch, and how likely illegal it is to connect to and use networks without permission, this is definitely an urban legend.

I don’t know of this is happening, but I don’t see how a small automatic updare couldn’t “add this feature”
Considering how easy it would be to catch,
how easy it would be?
