TCL has sketchy direct connections with the Chinese government as it is partially owned by them and the communist government has heavily subsidized them to grow their market share.
U.S. Department of Homeland Security has been investigating back door security issues in their TVs since very late 2020. I assume being they are still allowed to be sold here and still allowed into the google play store it is ok.
I believe some hacking groups found some back doors but Im not interested enough to care, just throwing this out there.

Intentional or not I guess depends how much you trust the communist government. I do think if it was serious they would get banned like Huawei did regarding cell phones in the USA. Then again, maybe not if concern for retribution against USA cell phone companies of which I think Apple is the only one left.
I had a Huawei phone BTW, loved it. Sold all over much of the world, the new ones very nice also Now the Honor (brand) it no longer is part of Huawei and nice looking phones.Huawei still makes nice phones, not sold here.
