Oath is killing off Yahoo Messenger on July 17
Found on Betanews on Friday, 08 June 2018
After this date, chatting will no longer be available, and users have just six months to download their chat histories. At the moment, there is no direct replacement for Yahoo Messenger, but users are being advised that they can request an invite for the beta version of the invite-only group messaging app Yahoo Squirrel.
Most likey not every user of Yahoo Messenger was aware that everything they send to their friends has been logged. That's some huge collection of really personal data.
