In addition to all the other good points here, mentioning Zoom and the others also makes the story more vivid and "real" to people, which is important when you're competing for attention, clicks, and shares. You'll notice the headline would've basically been complete & sufficient after the word Coast: "Big Internet outages hit the East Coast." But just in case there are any Homer Simpsons out there unable to imagine the impact of such a thing, they're letting you know, that thing you think of as Zoom is actually the internet too. Also if you mention Zoom, you can then go on about how Zoom has "become essential" in these unprecedented times when we're all in this together now more than ever stay safe. If you're the type to get worried or outraged, that contradiction between "essential" and "not working" is a better magnet for your worry or outrage, which again makes you more likely to read & share it. I think editors have this stuff internalized and do it unconsciously. My cynicism about it has reached rather a sobering depth.
