I have a different view.
Have all governments move straight to FOSS federated platforms, so that the billionaire that caused this exodus (Musk) is eaten alive by other billionaires so that they learn that when they duck up, the entire billiobaire class loses revenue, so can have some class infighting for once.
If one billionaire’s F*ck up leads to another billionaire’s increase in fortune (Bluesky), then all you’re rewarding is them to keep manipulating people into hating each other’s platform.
There’s no such thing as “target” and “non-target” billionaire. They all are targets.
