The author seems to live in a bubble where people are aware of RSS feeds. This article is the first I'd even heard of ICE in the first place. While multiple companies are listed as being behind ICE, no examples are given of websites that actually provided a feed for it.

Meanwhile, RSS is barely relevant today. For decades (Youtube turned 20 this year), people have had access to feeds curated by "the algorithm" operated by a commercial interest (hoping to maximize the amount of ads you look at); and most people seem to prefer it that way, if they're even aware of alternatives.
