The point to disable infinite scrolling is more nuanced, though. The right implementation is correct pagination, that allows you to start reading where you left off. The whole reverse-chronological timelines are a feature to bind your time.
With current systems, you start with recent posts and scroll down in the hope to find where you left off. You have no idea how many posts are in between, and you probably read new to old while scrolling back.
With the systems demanded, you have a permalink to your reading position, and continue reading forward (more useful and natural), have a page number how many pages you have to catch up (if you want to read all) and no FOMO about gaps you cannot bridge because you can only scroll back a certain number of posts.
You have little time the next two days and a whole day off after? Just catch up with the news on the third day, no need to try to catch up every evening to not miss out on something.
