Oh yeah, I completely understand. I'm not necessarily in favor of forced bundling. All I'm saying is that sometimes there are benefits when there is a single vendor who can do tight integrations. Apple being the other obvious example with their (supposedly) seamless hardware ecosystem integration.
In theory, something like Linux has a good model with multiple distributions, with each making different choices for the end-user. In practice, only a handful of distributions get any kind of traction and/or support.
