2 out of what, 50 games? I'd rather the focus of their message was DRM-free in upcoming titles rather than the 2 titles they "liberated". The real accomplishment will be getting newer titles without DRM on there and that's what will draw me to the service if they can do it.
First of all, your splitting hairs on the whole "Copy Protection /= DRM", but that isn't really the point. You are now trying to defend your original statement of the "attention whoring" when in-fact the company has at least 2 games on the service with original DRM stripped, which in itself allows them to make that statement about being DRM Free without "Attention Whoring".
Secondly the company itself is selling games through a digital distribution method without including DRM of their own. Thus also allowing them to use the term DRM Free without the so called Attention Whoring, most (if not all) of the other sanctioned Digital Distribution services for games do include DRM of their own or the original in some fashion. Just admit that your original accusation of the company using the pitch for attention whoring purposes was incorrect.
As far as whether or not the "DRM-Free" sales pitch means anything to you doesn't matter, it will to a lot of others, and is a completely valid feature for them to point out.
