Because companies killed the ability to subscribe outside of their walled gardens when they killed off RSS. This was a strategy they executed and were successful.
Literally commenting from Unread RSS on an iPad, the app I use to consume all my news from a few dozen sources that range from HN to NY Times. It’s not quite as simple as it was, but it also wasn’t ever exactly ubiquitous.
Nobody has "killed off" RSS. It still exists - there are still plenty of RSS clients of all varieties, and many blogs/websites, including YouTube, provide RSS feeds.
Youtube hasn't killed off RSS yet but you have to go way out of your way to find feeds. They will kill it as soon as they can do it without causing too much of a stir, it's certainly Google's overall strategy to discontinue RSS.

I've been hearing this for literally more than 5 years. Nothing was stopping them from removing it after they killed Reader, and they still haven't, a decade later.
