Are you trying to pitch RSS against privacy enhancing technologies such as NoScript, TOR, etc.? The point is rather that more privacy is a neat side effect of RSS, not its primary purpose.
The primary purpose of RSS - aggregation of content -- works very well, irrespective of bad UI decisions which have nothing to do with RSS itself. And when you pull a full text RSS feed, you're probably far away from "Like" buttons and the like while reading content.
RSS is an exchange format, nothing more. Don't conflate it with some historical transmission methods, nor ignore cases where it's behind a paywall, nor embedded tracking images (since nearly any reader will allow images).
Privacy has nothing to do with RSS. Some feeds I subscribe to have JavaScript and Flash - where's the privacy there? Some are behind paywalls - I'm identified by logging in, and even more so by providing payment info to be able to log in.
Thus, by losing RSS, we would lose zero ability to read privately. It's only viewed as being without all the privacy-sniffing bells and whistles because most providers don't do so. RSS can lose all its currently-common privacy attributes while still being RSS. We should be worried about the loss of privacy online, which is rampant, not the loss of RSS (if it does die). And RSS is a particularly bad flagpole to gather around; anyone up in arms about it is much more likely to be up in arms about privacy than the reverse.
