The philosophy of biology literature offers several arguments aimed at showing that information theory is conceptually unsuited to capture the informational talk in molecular biology. Such arguments led to the consensus that, if the informational talk in biology can be defended and explained at all, we need a different strategy. The debate, in fact, developed mostly along this line. However, recent contributions seem to (and even claim to) challenge the consensus and thus to vindicate the role and relevance of information theory to this particular debate. In this paper, I examine the main arguments leading to such a consensus and I analyze the extent to which those recent accounts actually succeed in vindicating the invocation of information theory. I argue that these attempts fail to vindicate the information-theoretic strategy and, therefore, the consensus remains unaffected by them.
