If you buy a product that someone can remotely control, then you are setting yourself up for a world of hurt. Whether that is advertising or having all your data wiped (like is currently the case for those Western Digital Live Book hard drives).
'Future blaming' is an asinine term. If you point out to someone that, well, they shouldn't be surprised if their home got robbed because they only had a screen door, you could make a similar reply that you're "future blaming" those people because they needed to "to predict all possible eventualities and are to blame for any future changes to a system?" Ridiculous.
People need to take accountability for their purchasing decisions. You buy a product with a gaping front door in it that allows the vendor or whoever else to push whatever crap into the product? Then that is on you.
To take your example to the extreme, unless people control their entire tech stack, they deserve whatever is coming to them.
So if the software you're using on your system breaks functionality or introduces ads, it's on you. Maybe you can reject software updates to your local stack that you're aware of, but what happens when stuff is introduced in part of the stack you can't control?
You also assume everyone is sufficiently tech aware to prevent such things. yes, in an ideal world, every one is sufficiently tech savvy to know all possible eventualities. But that's not the case, and anyone here who thinks they're infallible at doing so, is kidding themselves.
You're assuming everyone is sufficiently tech savvy however to understand this could happen. Unless you're going up to every would be buyer and telling them "hey in the future this product might have ads...but also all the other high ends brands might have ads too..." then you can't expect the average person to really prepare for something like this
In the end you didn't you read the fine print where it said google can make changes. You relied on their brand name and popularity and thought you were making a solid choice. You will get outraged today and forget about it tomorrow.
You got played. You were scammed. You are a victim of following what society told you.
This is such an absurd take on things. So every change should just be brushed of and people should just move on? No software company is open to criticism for their changes and it's the consumers fault for not understanding every little nuance?
Trusting google to control your tv experience is not the same thing as trusting any company to provide any service.
These changes were foreseeable so much that it is written in the agreement. You have no legal recourse.
To spoil the next discovery, your tv habits are or will be monitored and recorded now or in the near future. This information will spill into your life in unwanted ways.
