According to this article here [slashdot.org], no messages were changed:
If ANYTHING about the message is altered including delivery schedule, mix of content, etc then they are altering the message.
Please define "message".
It may refer to an item in your facebook stream. In which case, nothing in the messages has been altered.
Or "message" may refer to the the facebook stream as a whole, made up of the smaller individual message items by your friends and/or advertisers.
In that case, facebook is the sender of the message and the "message" always has been subject to facebook picking news items. We basically had more than one algorithm (or parameter sets for the same alogrithm) that picked those messages. And as picking messages (or message items in this definition) out of all those potential messages sources (friends/groups/pages, whatever you're following) has always been the core of what facebook made to create its message (the stream you're seeing) there is not much new here either.
Not everything about a message is the simple content. When you send a message and the tone you use is every bit as important to correct interpretation by the recipient. Facebook altered the messages without actually changing the specific content. If the message was unaltered (including delivery, tone, timing, etc) then we would expect reactions to be identical.
i agree that context is essential for "messages". But when you're posting something on facebook to your friends, you never had control when, where and even if it will appear in other users stream. So the context in which your post may or may not appear is not under the senders control and therefor not part of the message.
Could you please give an example how facebook could have changed a message (and not the delivery context, which has always been under facebook control) without changing the content?
But this line is crossed thousandfold already.
Even if true (which I dispute) it is irrelevant. Just because others do it doesn't make it acceptable for Facebook.
I never said it was acceptable. I said it was widespread. And I put that line where you're manipulating someones emotions for commercial gain without their consent. (When I'm watching a comedy, I WANT my emotional state to be manipulated)
