That's a really odd way of looking at open source software.

Mastodon is just an interface for the larger Fediverse network. It does not control the network any more than Microsoft Outlook controls the email network.

Similarly, email is a "nazi friendly" technology. Are you going to not use email because of that? It's not reasonable to base every choice in your life around whether a "nazi" could potentially make the same choice.

If only there was a decentralized social network where you can choose who to federate with...

Is Windows already banning all nazi users?
