Either way all this is going to reach a head come the 8th of June.
If you log into battle.net today you will notice that up the top is something about a new updated battle.net agreement.

In there is a paragraph on how the "Real Life Friends" works. It stresses what they can see and can not see and makes deliberate use of the phrase "Real Life Friend". As in if they are not your RL friend don't use the feature.
It makes it clear that if you don't wish to agree to the agreement that you can stop using the Battle.net service. Which is used to connect to World of Warcraft. That you agree to this TOU and World of Warcraft's TOU & EULA. That if "If any part of this Agreement is determined to be invalid or unenforceable, then that portion shall be severed, and the remainder of the Agreement shall be given full force and effect.".
So I hate to be that guy running around with a slippery slope argument decrying about how this is going to result in canceled accounts , the invetiable result of pretty much every change Blizzard has made since the pre-alpha days but ....
If they don't update this terms of use to accommodate people's privacy concerns IMHO they will either see a ton of cancelled accounts ... or a feature that never gets used by anyone as everyone refuses to use it until their privacy concerns are addressed....
