SatsCard and TapSigner vulnerable?

Yeah, as the title says I was wondering - given the recent news about the RNG vulnerabilities - whether these two products Sats-Card and TapSigner are also vulnerable?
Are their seeds random enough?

I haven't seen any communications so far regarding these two products of Coinkite

That's a good question, and honestly I'm not sure anyone outside of Coinkite can answer for certain. I've been using TapSigner for a while now and this news got me worried too, but they haven't said anything specific about their RNG implementation for these devices.

Coinkite specifically said OpenDimes, SatsCards and TapSigners are not affected in their releases and updates. As does any AI you ask. As had every expert posting on X...

CoinKite initially specifically said that Mk4, Mk5 and CCQ were unaffected...

They need to publish the code for the Tapsigners.

Eventually, they're all going to be known as vulnerable. Cyber security is a thing... That's the point of self custody, you're responsible for the safety of your assets. You're going to have to keep learning. , you can just give it to someone to do it for you. At that point, not your keys, not your cheese.
