Both the article segment you quoted and your comment seem to lay claim to the "purpose/point of RSS".

Is there some inherent value in having isolated the point of $thing, for all or even a majority of users, that makes it so desirable and common in discussions? Is the author's experience with RSS improved if they read your comment?

Both of you have identified a workflow that works for you; it seems useful to share "I've found that subscribing to too many feeds means if I'm not careful, I'm overwhelmed by the number of unread articles", or "I solve this by prioritizing what I read from my RSS feed and by accepting I won't get to all of it".

But when the pitch is ~"you're using $tool wrong, what you need is a shift of perspective in your mind," it comes off as far more combative than I suspect you intend to be.
