Seems like they provide a lot of freedom.

How many VPN, TOR, LN, and Bitcoin nodes are run on Raspis? How many people have cut their Linux teeth on a Pi? They made cheap computing accessible to the whole world.

I'm experimenting with start9 on a Pi, and I've been running my own private Nostr relay, getting bitcoin set up, and hosting my own file server. I wouldn't have been able to do that otherwise.

I'm no expert on wallets, but it seems like the consensus is Coldcard is super secure. Getting hung up on not being 100% open hardware seems a little picky. Perfection is the enemy of good.

Is the world less or more free with these two devices?
