Collaborative in what way? Are they collecting, storing, and sharing user data with government agencies upon request? I am sure they all do that. Companies (crypto-related or not) have to respect local laws and regulations and aren't exempt from them. Maybe you are talking about the Address Ownership Protocol (AOPP) they support when you said they collaborate with the government.  

Trezor IS fully open source, it doesn't have secure element yet, but it works just fine and can be used with passphrase.
Bitbox is NOT collaborative with authorities, and I never said that, it's fork of Trezor wallet with secure chip integration.
I don't like satodime so much, but you can do your own research and don't ask same questions multiple times.

Dude I am not your babysitter so do as you want with your money... you are not purchasing rocket to Mars, and I don't like repeating myself

Hmmm yeah I see what you are referring to :/
This was probably my mistake with table information and I corrected it now.
According to Tangem sources I found, only app and NFC communication protocol are open source, everything else including firmware is closed source.

You don't really need to have support for lot of coins because most of them wont exist in few years.
Best comment I saw about this is like you are using highly secure vault for storing bunch of bananas aka shitcoins, they will all be rotten soon enough.

I would say that Bitbox, Keystone and Trezor are your the best choices for hardware wallets in 2022, that is if you want to have support for Bitcoin and other altcoins.
Everything else is not recommended by me, but you can do whatever you want with your money.

In case you didn't saw or read correctly, I created the this topic for list of Open Source wallets, and I am not talking about applications but about device firmware.
If you have more information that Tangem released their firmware as open source please post them here.
Until then I am not going to recommend anyone Tangem devices.

Tangem has crypto cards, but they also have hardware wallets that look like cards, but it's true they are all closed source devices.
