Sorry for the bad quality.
My grandfather had this in his office. He worked as a computer engineer so I initally thought it was a zoomed-in picture of a computer chip or something, but maybe it is something large.
He's not alive anymore so I can't ask him. If somebody can help me out, that would be great.
The shocking news this week was that a couple of admins of large Mastodon instances were talking with Meta (under NDA's!), so it seems your hope (and mine) will be in vain.
Truth.social was actually never part of the Fediverse. It does use AcitivtyPub, but it doesn't federate with other instances: https://pocketnow.com/trump-truth-social-network-removes-most-freedom-friendly-features-fediverse/
Good news for scammers
On Mastodon there was this whole thing about users calling themselves Twitter refugees, and people expressing their displeasure with the term. It does feel a bit inappropriate to equite youself with actual refugees. We're just moving from website to another.
