I've got some bad news for you, Walmart acquired Vizio two years ago:
"This acquisition is not merely about expanding Walmart's product lineup but rather part of a sophisticated commercial strategy to integrate its retail operations, owned media channels and TV hardware into a cohesive ecosystem. This ecosystem is designed to generate and share data, influence shopping behavior and, ultimately, drive sales through an innovative approach to advertising..."
"...By owning a television manufacturer, Walmart can now directly serve and, crucially, measure the impact of ads on consumer behavior. This capability significantly enhances Walmart's potential to convert advertisements into retail purchases."
Only saving grace I have is that I bought my P659-G1 in 2019. While it doesn't prevent bad updates, it's a little less likely they pushed deep changes to old models.
And I can't believe it's been over 6 years since I had already eliminated Samsung for their ad behavior, and not only have they not changed, they've doubled-down.
But Samsung's ad behavior led me to buy a Vizio TV instead.
