Isn’t Coldcard open source?

It’s code viewable
Which ones are true open source? Seedsigner?
Jade, SeedSigner, Passport
Sparrow, Samourai, Green
Start9
The big offenders are Coldcard and Umbrel: these things have huge market share without honoring #Bitcoin's open source ethos.
I'm disappointed in myself for not doing more research. Currently running Umbrel, but soon switching to Start9.
It is.
The only real problem with coldcard, and I understand it, is an ideological one.
Their code is protected by government. You cannot use it to sell a product and make money with it. Not a fan of that but this is not a security problem.
Unless I'm mistaken, but I don't think so. Willing to accept to be proven wrong.
