I think we mean the same thing, yes. (See my response to a sibling about newsletter hosts building interest profiles[1].)
The PO box analogy kinda falls apart unless you use a separate PO box per subscription but you're right, email aliases protect you from any kind of advertiser profiling. Feeds are just nice because they're simple HTTP requests so they don't have that problem in the first place (unless you're worried about IP-based tracking and don't use any kind of proxy).
