Man this thread has been going on for a while now...
I did a bit of searching around on why RSS was removed. It wasn't until recently I also had realized that a lot of big sites are slowly moving away from RSS opting for having their content be read through Facebook or Twitter or some other social site. I don't know the full decsision on why they are doing this but it seems to be a growing trend of mixing news content and your social circles.
I think Apple has taken notice of this growing trend and went ahead and removed support for RSS because of this. You see that they are integrating Twitter and, soon, Facebook into OS X. You can almost get the same effect of RSS with Twitter by following all of the news content that you would normally get with RSS.
So I wouldn't blame Apple on this. Blame a changing market. Apple is just following in the footsteps of trending movements. RSS is slowly going away. Most of my most visited sites have removed RSS in favor of social networks.
Again, I don't know why people want to mix news content with social circles but apparently they do and that is where it is going.
EDIT:
Also recently read that even Google Reader will sooner or later be merged into Google+. For now it stands alone but even it will slowly go away in the near future.
What I'm starting to do is move my Google Reader subscriptions over to my twitter account. I don't use the account for much anyways. I'll keep Facebook for friends/family/etc and keep twitter for news. For now.
