Almost everyone I've worked for in enterprise and defense, for starters. A couple places didn't allow chat applications that recorded history (too much liability during legal investigations was the excuse I heard). Doesn't mean that these policies weren't violated. This isn't the worst I've heard by far though. A lot of places won't give developers even power user access to their own laptops so you need to request installation of every application you might ever want, including git, Cygwin, etc. Many places will not allow users to run VMs either (and will disable VT-x mode in BIOSes that are locked out).
