As someone who currently has their photo on a company's 'About Us' page, I hate it. Why does anyone care who the nth developer is? Let me just do my job without forcing me to be publicly listed for spammers and scammers to target me.
It's super useful to potential hires about the kind of team you're building. Especially if there's some kind of niche you're in (product, tech, region, whatever). There are people who I would climb mountains to work with, and others within a niche whose very presence in a company is enough to steer me away. Another signal for me is the fraction of xooglers in the engineering team.
