I think that this is the best take on this topic

Why?

But that is a double-edged sword. What if, for example, mastodon.social doesn’t defederate with Meta, but you defederate mastodon.social? Now you’ve just cut yourself off from a huge portion of the fediverse. Admins should defederate from Meta if their community wants to do that, but defederating from other instances that didn’t do that is going a bit too far, in my opinion.

Are other single board computers like OragnePI or Libre Computer any better?

It can but given how media is ignoring it I dont see that happening in near future. Us user will have to shape the future of the fediverse and I think that is the best thing.

Or you can use duckduckgo that uses bings search index while protecting your privacy
