Yahoo Forcing Upgrade on IM Users
While the forced upgrade's purpose is to combat spam, it could also disable third-party IM clients and services.In an effort to combat spam, Yahoo Inc. is requiring users of certain older versions of its Yahoo Messenger instant messaging client to upgrade by Sept. 24 or lose access to its popular IM network. But the move could have a side effect that company officials say was not the intent of the move: It could disable third-party IM clients and servicessuch as Cerulean Studios Trillianthat commonly allow users to connect into multiple IM services at once.
Yahoos forced upgrade push comes a month after Microsoft Corp. started informing users of older versions of its MSN Messenger and Windows Messenger IM clients that they must upgrade by Oct. 15 or lose access. Part of Microsofts move also was to block third-party IM clients and services unless they obtain a license to connect into its .NET Messenger Service.
