>L;DR- TVs are using their own cellular connections

The link doesn't say that.

It links to https://venturebeat.com/2019/05/01/huawei-reportedly-plans-f...

And it opens with,

> Though its 5G products are not entirely welcome in the United States, Huawei is reportedly pushing forward with a unique new product: the world’s first 5G television. As Nikkei reports this morning, the Chinese company plans to use the cellular-enabled TV and new PCs to challenge Samsung’s and Apple’s dominant positions in the global consumer electronics market.

That's not really what's being talked about, though. The fear is that if you don't connect your TV to your wifi network, it will have a secret, hidden LTE radio that it uses anyway.

It doesn't seem that Huawei is being at all secretive about this; they are advertising it as a feature.

You're ignoring the part where Samsung TVs are actively connecting to open networks.

That's a single TV, also is this on the market, the link said "reportedly"?

The other comment is also correct.
