When I first purchased my TV there were no ads on it. The ads came later when Google updated their Android launcher. So, where's my discount?

Why do you think Google - an ad company - was trying to get into the TV market?

I don't have time nor the information to second-guess possible future motivations of every company in a supply chain before buying a product. Most people won't even realise Google provide the software for a lot of these products.

Yes because it takes great insight to know that a Google based product probably exists to gather information about you for targeting advertising. It’s not like Google is some obscure company.
