This is not "enshittification". That implies it's gotten worse over time. Smart TVs have been doing this from the beginning.
Smart TVs are the enshittification of regular TVs. An attempt to extract more money from the customer without providing a useful benefit.
I disagree. It's definitely gotten worse, notification ads for my TV for example.
LG also didn't used to have home screen ads, but that's a long time ago now.
