The reason of the data-sharing is to help Facebook to target advertisements and friend recommendations and to allow businesses to communicate with users. The messaging service announced that new services are coming and soon users may receive flight status information for upcoming travels, receipts for goods purchased or delivery notifications.
This change will improve the advertisement experience on Facebook and also fight against spam and abuse.
The messaging service has ensured that it won’t sell or share phone numbers to advertisers. Furthermore, data shared with Facebook won’t be posted on the FB social network.
The two consumer privacy groups said that the policy changes violate an agency directive following Facebook’s acquisition of WhatsApp that the company must get opt-in consent from consumers. Instead, under the new policy, the responsibility is on users to opt out of the data transfer.
