We'd hope that this will get enough of our users
exposed to and interested in Blender so they will
be inclined to work on Blender plugins that would
talk to Steam's backend services
Recruiting you say? Certainly so, they appear to be taking volunteers.
This is integrating a free 3d package with a very popular game distribution network. The plan is to essentially just have a link from steam to a vanilla download of blender, and they hope there will be more of a community built up around it.
I have absolutely no idea what you're complaining about or how this could be a bad thing.
The plan is to get that, and let the community to their work from thereon. Not necessarily a bad thing, but I (for one) wouldn't want to do their job for free.
