I know the Rod reference is a joke, but I maintain my argument that Rod is no entrepreneur or marketing genius, he's just tight fisted, assertive and good at organising things within the sphere he's comfortable with. This worked a treat in the 70s/early 80s when he was managing a pub band that went 'big', and the music business was about face to face-or telephone negotiations with inside-the-box-thinking record company execs and tour promoters, with a certain amount of casually talking tough with anyone who was being obstructive.
Either he's a hands-off manager, waiting for Maiden (Steve) to suggest a vague direction, or he's out of his depth with modern business opportunities and the online media circus. Either way, Maiden doesn't have a whole lot of direction commercially, other repeating the same formula over and over again. Branded beer has gone from being new and clever to being 'oh god not another one', and that phone game, which was a great idea, has been done to death and looks old when they could have launched other games. There was an entire captive audience during lockdown and Maiden's online presence is dismal. They might be big-money, but they're also not adventurous.
It's probably not in the interests of the band's image to have anything as naff as branded cereals (Trooperbix, anyone?) but they have so much more potential that would involve minimal or even no input from the band. Look at Adrian's web appearance a few months ago, so easy to do, a nice personal contribution that fans value.
