My understanding of the issues with Ledger:

1. It’s Closed Source vs Open Source which is a no-no to Bitcoiners especially people on Nostr

2. They suffered a hack last year because of a bug in their closed source software which raises questions about their code. https://fortune.com/crypto/2023/12/15/ledger-wallets-drained-in-cryptos-latest-embarrassing-hack/

3. Some of their decisions have been against the ethos of Bitcoiners. Like having a recovery tool for your seed phrase. https://www.bitdefender.com/blog/hotforsecurity/ledgers-recover-feature-sparks-controversy-amid-security-concerns/

Overall, I think they’re a company trying to solve difficult Bitcoin issues as a profit making company. But they aren’t everyone’s cup of tea.
