Tech companies including Adobe, Apple, Dropbox, Sonic.net and Yahoo earned top ratings in the Electronic Frontier Foundation’s annual report on data collection practices, while others such as WhatsApp and AT&T landed at the bottom. The report analyzes how companies handle government requests for customer data. The companies are evaluated “based on factors including their transparency to consumers about data requests and data retention, as well as their public positions on so-called back doors that grant government agencies access to customer data,” reports The New York Times. The EFF’s latest report suggests that tech companies are generally improving in this area.
