Foundation did not rip anyone off, Coinkite did the same thing to trezor - it's called open source for a reason lol. I'm recommending you use Open Source products as that is the future you wanna see and the present you want to be in. Open Source devs find bugs in code all the time, which they did find really bad ones in Coldcard in the past. Now you don't have that luxury because coinkite also has a reputation for not paying bounties. For the shitcoin part, That is highly irrelevant as Trezor is the oldest, meaning the most reviewed Bitcoin Hardware Wallet Source Code out there. You'd be a fool to dismiss it with respect to prepackaged HWWs. I personally am a SeedSigner maxi, if you build it yourself.
