Yes, unfortunately this is the case (I work for ebooks.com). Most publishers require us to use DRM and Adobe DRM really sucks, but there isn't other options out there and we don't have the resources to make something better.
We focus quite a bit of effort on educating publishers about moving to DRM-Free as it makes everyone's lives easier and from what we've seen increases publisher sales numbers.
