As a seasoned crypto analyst with five years in blockchain infrastructure, I find Ledger's abrupt end-of-life decision for the Nano S deeply troubling. With over 4 million units sold and $1.18B in lifetime revenue, phasing out support isn't just a technical constraint—it's a breach of trust in a space built on self-custody and open-source principles. Users aren't being offered alternatives; they're being nudged toward paid upgrades under opaque terms.
