How we write these. No hit pieces. Vendor memory is genuinely good at what it does, and we say so. The difference is structural: a memory owned by a platform has a reason to keep you; a key owned by you doesn't need one. Every claim on these pages is checkable against our privacy policy, the open format at usrkey.dev, and the principles at usrkey.org.
