Just about everyone seems to agree it should be configurable, but most
(90%? 95%?) users won't ever change it from the default. Your employer
appears to have chosen a diode configuration by default:


and on top of that has put the option in an "advanced configuration"
section that requires the user to jump through some complicated hoops to
get to:


So, for data points we have:
* Free has open access
* Google has a diode-style firewall enabled
* Most American ISPs (Comcast, AT&T, Verizon) are bring-your-own CPE, so
they don't set policy.
Any other large deployments with a policy?

Personally, I'm on the open access side, for all the reasons outlined so
