name.com and name cheap are both backed by enom. name.com is explicitly owned by enom and namecheap is an enom reseller. Not saying that enom is an asshole, just that its a good idea to know who you are really dealing with. Both of these shops have to abide by enom's policies.
FWIW Namecheap are no longer an ENom reseller, they have been an ICANN accredited registrar since 2009. (I remember when Namecheap had to come to an agreement over the domain ownership between themselves and ENom when they were moving from reseller to ICANN registrar)
An email concerning my most recent transfer to NameCheap included the following line:
eNom, Inc. has received a request from [Me] on 22 Jan 2013 to become the new registrar of record.
The subject was:
Domain Transfer Request for [Domain]
The message included links at transfer-approval.com for verifying the transfer.
The whois information for namecheap.com shows NameCheap, Inc as the registrant, but eNom as the registrar (which may mean nothing at all).
So, there appears to continue to be a link between Namecheap and ENom, but it might be limited to NameCheap using eNom services and/or not updating account information to display the right info. It's easy to be a customer of NameCheap and assume they are a reseller or that eNom is the parent. If that's not the case, they have some work to do to clarify things. That said, I'm a happy customer.
I just spoke to someone at Namecheap and it looks like they didn't resolve the agreement issue over who owns the domains as despite becoming and ICANN accredited registrar they're still operating as an eNom reseller.
I guess they don't want to end up like Registerfly (a former eNom reseller, who got ICANN accreditation - which was eventually terminated) when eNom terminated their relationship with them, eNom gave Registerfly customers the ability to instantly push their domains into an eNom account through verifying and acting on the email sent to them including a free transfer so there was no fees to the customers.
Registerfly ended up losing the majority of their customers (through that and a ton of poor business decisions etc) & Godaddy ended up buying the remaining domains in Registerfly's portfolio [1] - it didn't acquire the company as ICANN was taking legal action against Registerfly for its continued noncompliance of the court ordered injunction.
