So that jerry0 could ask even more questions and feed his paranoia

I don't keep track of how often Ledger has a firmware update for S&X, but I know that in the past people have complained that there are too few of them (1-2 per year). As for the S model, the last firmware was released on November 30, 2021, and for model X the latest was released on January 25, 2022, before that on October 21, 2021.

I don't think it's necessarily bad, which means they're working on fixing bugs and adding new features - but no one is forcing you to upgrade your firmware if you don't want to.
