Lot's of people are throwing Google and alphabet in to the same bucket here. Please don't do that. The alphabet companies are free to be ran however they wish and Nest is an extreme example of NOT running a company the Google way. When the alphabet change happened, this became quite clear in just a few months time internally. What you're seeing here is further evidence of that.
I'm trying to explain (perhaps poorly?) that the change is not simply semantic. No one who is part of Google proper has any say in what nest, glass or those other companies do at this point. None of the culture, support etc... transfers over. The CEOs of these new alphabet companies are free to do as they please. What you're seeing here is this in action.
Saying Google are somehow accountable for nest or glass is like saying that dropbox are accountable for the actions of reddit. They are literally that disconnected now when it comes to how the businesses are managed.
Consumers don't care how about Google/Alphabet organizes itself. Google owns Nest; that fact can't be avoided. When you own a company that intentionally bricks their customers' $300 devices for no other reason that they don't want to support them anymore, you're going to have to deal with the negative perception that it creates.
In this case, being disconnected is a deliberate choice by Google. If that leads to problems, they're still responsible. You can't just take your hands off something and disclaim all responsibility for what happens afterwards.
It was a deliberate choice by the former Google board, who no longer runs Google and now runs Alphabet. The blame lies with Alphabet, not one of it's many subsidiaries.
I think the problem is that Alphabet is basically what we used to call Google, and what is now called Google is just one aspect of what we used to call Google. Referring to Alphabet as "Google" is outmoded but it's sort of like saying "Blackwater" instead of "Academi."
I think this is a little more tricker. When customers make buying decisions, there is "Nest, owned by Alphabet and not likely to be shut because they are broke" benefit that they get. When they fail to meet those expectations, it should and will certainly reflect on the trust for Alphabet. Mainly because of your argument: Alphabet has little control over the companies and one should stop expecting good treatment and product lifecycle just because it is under Alphabet umbrella.
What Nest is doing is little different to Reader or the other products Google killed. Alphabet is the common link and is clearly OK with this behaviour.
