Similarly, their TVs are known as probably the single most obnoxious devices on the market right now, and are always in the news for finding some new and obnoxious way to push more ads or more intrusive ways to spy on you in general.
Everyone always asks this about Apple but really it's never seemed more relevant than with Samsung: why are you purchasing hardware from a company that very very obviously does not respect you as a customer? Aren't there any other android vendors you could patronize instead?
(to be fair, if you aren't interested in budget hardware, and you won't buy a chinese phone, I suppose that list isn't all that long. you have... google and sony, I guess?)
