I work for an agency that is part of a (very) large holding company. The IT dept for the holding company mandated that all agencies within to host their WordPress sites in WP Engine. I manage the sites for my company and two sister agencies, and just between the three companies there are 18 sites, not including the Dev/Staging variants! There are over 1500 agencies...granted not all have WP sites, but I am certain that many do. So if this reflects on the IT manager who made this call, it would be hugely magnified!
