You do not need a billionaire or a VC fund to use social media.
They are just middlemen opportunists trying to insert themselves between you and your friends.
The Internet was built to make it easy for you to connect with others, and that is getting easier with protocols like ActivityPub.
You don’t need Elon Musk. You don’t need Mark Zuckerberg. You certainly don’t need any Silicon Valley tech bro to let you use social media.
