I have loads of RSS feeds and I almost universally use them as notifications to go and see the post on the full site. Most RSS readers I'm aware of prominently include an option to view the full page, often inside the same app (and these apps are less likely to have content-blocking add-ons installed, which would block lucrative surveillance). I'm quite happy for RSS feeds to include only a summary/thumbnail/excerpt plus a link to the full page.
