In fact when I use reddit from my phone (through Firefox) I force it to use the non-mobile version as I find it much faster (as long as you open every link in a new tab).
I understand the need for such verification when a webmaster wants to prevent easy re-registrations of trolls and/or banned members, and it's still better than Google's invite only system for when they release something big like gmail or g+, but it's a dark pattern all the way.
(On Android, Hello gets access to your contacts, your rough location, the ability to read and modify your storage, use your camera, and view your Wi-Fi connections)
I understand why it wants contacts, to make it easy to add people, but again, it can be done in a "let the OS offer the contact picker" way, if we're making a privacy-respecting app.
If Google is expected to be the steward of protecting users, they should not allow apps on the Play Store which don't use the most privacy-respecting method possible to implement the needed functionality.
