the Fediverse really seems like it could be our response to these fuckers controlling the narrative on social media. It could be more than just an interesting decentralized social media platform. I really think this could be a key step in reclaiming our democracy.

Agreed, and I would add that finding ways to get nonprofit news organizations (e.g. ProPublica) and public media (e.g. NPR, PBS, etc.) to host and administer their own instances and to start directing their readers/listeners to those services would be a great way to advance this goal
