Of course not, but I don't believe most people I am friends with (or family) spend time really looking into products before they buy. Maybe a car or something? But a TV? When you can get them for $200-$300 at Walmart? Unlikely, unfortunately. So, that business model still works.
I realize my very small social bubble is not remotely large enough for an actual population sample, but I feel like it's just common sense. Things like Temu exist because this is a very common way of thinking.
Pretty much everybody replacing a TV that only lasted three years will choose a different brand next time. Making things that don't last is a good way to destroy the value of a brand
From an executives perspective is they don't destroy the brand for short term gains, the next guy probably will. So why shouldn't they be the one to benefit?
Only if consumers have a preference for TVs with short lifespans, which they don't.
