Many people who have switched from batteries-included, purpose-built blogging stacks like WordPress to e.g. static site generators (or similar roll-your-own setups) don't have a feed by virtue of the fact that the folks publishing those sites haven't gone out of their way to write the feed template. This is not unlike any other subject where participation comes down to opting in versus opting out.

That isn't to say any claims that feeds are almost a thing of the past holds any water. There are almost certainly more feeds now than at any point before. The second derivative is probably a flat line, though, which is what I imagine is behind the perception of deathliness. Feed consumption, on the other hand, is almost certainly down—but only if you exclude podcasts.
