Yes, I'm sure that's a factor too. Also, one of my first reactions was, unless you have an explicitly comedy kind of channel, maybe somehow audiences don't seem to reward British-style quirky humor that Map Men is full of. I love it, but maybe it causes people to feel it's not "professional" or professor-ly enough? Tom Scott definitely doesn't do humor, at most only wry ironic suggestions. The Map Men sponsorship endings themselves have been hilarious (Surfshark, NordVPN, Audible, etc).
