What's really shitty, in my opinion, is that they're giving 3 days notice, and only 7 days to download your chat logs for those networks. (For those unaware, retrieving your chat logs has been a feature of IMO for a very, very long time).
Because I need 4x hangouts (1 per company I work with, contracting, my own business, personal, etc) and many of the other apps either won't work with other clients, or have crippled features or usefulness, I end up running 10 "chat" clients.
