Re: Verizon had already (somewhat inexplicably) identified Yahoo!
Only if you aren't a Verizon subscriber in the US. Not sure about elsewhere, but in my corner of the world your Verizon email comes form Yahoo!. Verizon doesn't provide it on their own. So at the very least Verizon needs their email service.
Yeah, Yeah. You and I know it would probably be cheaper to just build a new one out from the ground up (not to mention the improvements in service you'd get), but that isn't in the DNA for one of these big corporations.
