What we need is this one simple trick:
A site that scrapes, collates, and de-dups your friends’ posts on every social media site, and then shows you the union of all of those posts as one feed.
This is the only way to break Facebook’s back: to allow your friends’ transition from one social network’s data silo to another to be so gradual and effortless that you don’t even notice it happening.
The thing that makes this difficult, of course, is not the coding, but the fact that if you succeed at it in any meaningful way, the sky will blacken with lawyers, and the data silos’ spending on technical countermeasures will absolutely smother you.
Sadly, people have little agency in all of this. Social Media’s End User License Agreements (EULA) and Terms of Service (TOS) make that clear.
