maybe so, but jeez. do you stay with any coldcard after this, if it's true that it's a device vulnerability. or is any RNG at risk? i remember how "safe" i felt after learning how big a 256 bit number was, hope that's still the case.

This was a firmware vulnerability, not hardware. Using the dice and the BIP-39 passphrase isn't a luxury. RNGs are often weak, also - and especially - the on-chip hardware ones on small devices.

A good set of dice always beats a hardware RNG, unless maybe when you've got a SiPM.
