I found the USA article interesting; especially since it was written by a law professor who appears to specialize in copyright laws.
The situation with the Google product looks to be somewhat unique. Maybe their lawyers told them if they have a financially unsuccessful product that they are not going to update or support anymore, yet allowed it to continue to be used by the folks who bought it, they could be liable for damages and they'd better shut it down. Who knows. Gadgets that control things like lighting, A/C and heating, etc. could go haywire if not monitored, upgraded, fixed, etc. by Google anymore, could perhaps harm someone, or even burn down their house. I feel this could well be the case here -- to absolve all liability from using the product anymore, so they HAVE to shut it down. It is kind of crummy that it appears Google is giving the owners of the product no booby prize for the device having to be shut down by perhaps not even giving them a $20 credit at the Google Store.
I was also appalled that the OP who was just expressing his concerns, got trounced on verbally by a Pot accusing the Kettle of being black and the OP was accused of "being unburdened by literacy skills you are ill-mannered and arrogant". (but, wait, there was more said above . . . )
Parker, give us a break; ever since you recently appeared in this forum, you have shown yourself to be exactly this way. Back off Dude, and let people ask their questions, voice their opinions and make their comments without you lighting into them like they just committed a major crime. You are giving programmers/software engineers a bad name, and Lord knows the general public regards them as being very likeable and sociable people for the most part.
This forum appears to be a one-man show, but at other forums for some major companies that have a raft of forum monitors, I assure you, you would have been asked more than once already to keep conversations friendly since we are all trying to help one another here.
