Laziness Helped Me Dodge a Bullet?

Owner of a Coldcard MK3.

I've always hated updating devices, my coldcard included. My MK3's firmware is still 3.1.9 .

Coinkites reponse says 'the issue relates to Coldcard Mk3 firmware versions 4.0.1 through 5.0.3'

1) Does this mean my seed phrase used an adequate amount of entropy in its creation?

2) Regardless, i've already moved my funds off the coldcard wallet.

3) Is owning an MK3 kinda of like owning FTX merch at this point?
