Article 1:

This is about AccuWeather using anonymous data from its users even after the user says they do not want to share their data outside of the app. The reason they were able to do this is because in their question they specified that they would not use the information through the app while it runs in the background, but they are using the anonymized data outside of the app. This article shows that apps have access to your data, which is not a new idea, and that they can use it without your knowing. 
Article 2:

The Amazon Echo Dot is a hands-free, voice controlled crevice that uses the same far field voice recognition as Amazon Echo.
