Not OP but I happily throw money at companies that help Linux adoption and more open hardware grow. I bought the steam deck, used it for a while and gave it to a nephew (I'm not big on mobile gaming), I've bougt the Pinebook, Librem 5, and will happily throw Valve more of my hard earned cash for enabling a more open ecosystem. We need to vote with our wallets or Microsoft, Apple, Meta, et al will gladly remove your ability to own your hardware.
it's good. think of it like adding a different kind of lock that requires a different key (method) to open up first. at worst it's no less secure than before. If it works as intended it's a huge disincentive for anyone collecting encrypted data with the hopes that a quantum computer may break encryption the "old" method in the future.
