Samsung, and some other major players put a lot of ads and bloatware in their phones, TVs, laptops and other appliances. Xiaomi doesn't have ads on global versions of TVs and Phones. I know the Chinese version does have ads.

As a homeowner, I don't know what is worse. Using stuff where the local government can watch and spy on every step or some Chinese guy watching your boring life if you are low-level person.
