Because the Followed feed is purely chronological. An interesting tweet from someone I follow could have happened 3 hours before I opened the app, and I would miss it.

This is why I preferred the old For You tab - it was (mostly) the people I had chosen to follow, but meant that I had the best content show up whatever time of day I opened the app. This is particularly important when I'm in the UK and most of the people I follow are in the US, so they're not tweeting generally at the same time I'm on the app.

I'm also confused. You can still see everything you've manually curated.

On the android app at least, a recent update made it so pressing the home button while you're in the "followed" tab switches to the "for you" tab. It's extremely annoying

If only there was any other way to visit a website.
