I am currently shopping for a cold wallet myself. I think anyone with more than 7 figure-sats needs one. I do care about the software being open source and publicly auditable.

More important than that is that people learn how to get non-KYC sats, though.

Because what's the point of keeping your sats "safe" if they're not safe from the state mafia sending armed thugs to take them from you?

Anyway, running my own node? Meh. If I had the space and the extra cash to keep a couple of machines permanently online, and the time to get knowledgeable and to maintain the machines...
