Removing the apps was the biggest solve for me. I still maintain some social accounts, but not having the native app reduces time spent considerably.

I am addicted to YouTube Shorts. It would be fine if it wasn't the first thing you see when you open YouTube. But often, I will open the app and then completely forget what long-form video I wanted to search for because the Shorts got me. It is insidious. The youtube app even asked me once - in some sort of survey - if I enjoyed seeing Shorts first thing and I said no. Nothing changed.
