Indeed. Feedly does a nice job of presenting rss items. I actually feel lucky that websites are still using rss.

I believe that this has more has to do with it being built into almost all CMS's than it being a conscious decision.

I remember creating a couple of years back a simple script where you input a subdomain or a top level domain and it would try loading the most common feed locations (like /rss, /feed etc.) and returns the location of the feed if it gets 200 as a response. All I had to do was to check for like 10 different locations (think: one or two for every major CMS) and it worked in like 98% of the time.

Yep, it's so simple yet too complicated for twitter evangelists like the OP.Also big tech companies try to push people into their walled gardens since data is wealth and they don't want to share it. In the end I believe open tech will prevail.
