I mean, I get what you're saying, but for a company with critical branding needs, they will absolutely be concerned by this. In many instances they might even notice themselves. Sure, your average software company CEO won't care, but if you're in the food and bev business, or a design firm, or a game developer, the execs are keenly aware that micromanaging their public image is essential. That's why they spend millions of dollars for logo redesigns, or in a more extreme case, spend a huge chunk of change to make their own sliiiightly different version of Helvetica like Target did.
