I am looking for informations about the authors of the current symbol used for Bitcoin. I am also interested about any brand design explainations such as graphic guidelines, and the way this symbol was adopted (contest, vote, imposition…). As a supporter of the symbol Ƀ, I am not sure this choice was right.

The very first icon (created by Satoshi) is visible here:

Satoshi later updated this using the B with two vertical strokes

He never posted much about why he chose this symbol. It was not in use before Satoshi put it in the logo.
The current Bitcoin-Qt logo was created by bitboy:

This logo replaced Satoshi's old one when the bitcoin.org GUI was rewritten from wxwidgets to Qt by Wladimir van der Laan. I don't think there was much discussion about it.
