The problem is, it looks like a child did it. Not a criticism per se, I personally like its design, but to outsiders (guys with suits), it looks somewhat amateur / immature (and these guys tend to care a lot about those things). And, yes, sometimes these people want to know what they paid for, whether they are customers (in b2b) or they are giving money (like a government agency or something), and a neat slide with lots of logos and oral explanations is often the way to go (pun unintended). Python's logo is an animal, too, but it looks clean and low-profile.

Unfortunately people do care that much about branding. On the bright side, the gopher isn't going away, it's only being relegated to a mascot role, like the Rust Crab.
