Also, sounds like a case of optimization creep - "I know a way to get even more revenue, we just sign up with this $more_shady_ad_network!". Displaying more and more creepy ads, no-one decreasing ads since they don't want to be the one decreasing ad revenue.
I returned a Bose speaker when it stopped letting you cast to it without their app, and have returned my Ring external camera when they removed customisable motion zones (I need to block a specific tree that moves in the wind). Plus more.
I’ve never had a problem doing so, I’m always polite and just explain that it’s no longer as advertised and print out the product update notes showing that they removed/changed x or y feature.
What? A month? Sale of goods act.
Then there's quite generous warranty for 2 years, up to 3 years, but that's when things break.
In addition, I think this also includes if a sold item is unfit for advertised use, or perhaps even if substantially changed during ownership (eg Samsung mandatorily introducing ads), but I've never had to use that so don't know).
I disagree with describing this as 'generous'. A TV manufacturer should guarantee that the TV will not develop a manufacturing defect for a minimum of 3 years, if not longer. I have CRTs that lasted decades (plural) without issue, while I've had multiple LCDs fail in under a decade.
There's nothing generous going on here, they're systematically making inferior products in order to drive an increase in sales.
