I am OK with the receiver being the one measuring the information content. If that message was supposed to say “brown fur” but was corrupted to say “white fur”, is this corruption detrimental or beneficial to the snow-bound boder?
Your carefully phrased question is ignoring the issue. Fur colour and accidental advantages are irrelevant. Random changes are always detrimental to information and everything you propose to keep evolution afloat must hide this fact.
