The fact that there's a highway to Hell but only a stairway to Heaven says a lot about anticipated traffic volume.

I have no crisis of conscience from clicking an vendor shortcut for a basic end-to-end Internet functional test. Or for teaching a User to do the same. This meets the business purpose locally and requires no $pecial effort from Users, network providers, or target systems. This precludes memorization of IP addresses by end Users thus reducing the offered load from the likes of excessive ping 8.8.8.8.
