Alexa and other smart speakers may endanger privacy rights

"“If you install a private corporation’s microphone-enabled device in your house, you should count on the fact that third parties may well access the information these devices detect,” Catherine Crump, co-director of the Berkeley Center for Law & Technology, said in an email.

“These companies wish to sell you things,” she said. “They do not wish you well. At the least, you can count on the fact that law enforcement agencies will be seeking court orders to access the data these devices generate in some cases. Do you really want the privacy of your home to depend on a corporation’s terms of service?”"
