In terms of solutions on an individual-level: after a lot of trial and error I feel like what works for me is an absolutist cold-turkey-approach. I've pretty much banned all consumptive screen-time except some things like Hacker News, LinkedIn, YouTube (only existing subscriptions, no recommendations or shorts etc). Things I know I won't spend more than 15-20 minutes on and are not highly stimulating and made to high…
It's not just Reddit that's like that, but it was especially striking after having been away for a while.
