But I will buy a Trezor T wallet because they promised that the secret phrase would not leave the wallet.
Don't be naive, Ledger said the same thing in the past, and today we know that the whole story they told is a simple lie. Trezor has its vulnerabilities, and even cooperation with companies that deal with spying on Bitcoin users and censoring transactions is not something that can position them as reliable producers.
There is one big distinction to be made. If you own a Trezor Model T, since it's completely
free open-source (
FOSS) as in 'freedom', you can refuse to upgrade the firmware, downgrade the firmware, write your own, and patch new firmware versions that have features you don't like.
You also are able to tell whether they try to sneak in some unwanted features and know whether new features are implemented securely, if any encryption used is secure.
If we just take one company who in a way betrayed its users and extrapolate it to all the companies, there is no wallet you can buy, no Linux distro you can install etc.
I would still not recommend a Model T right now, but at least if I got one, I knew what I'm getting, since code and hardware are open.
