Local first is almost equates to both privacy protective and public software good. Essentially antithetical to capitalism, especially America's toxic late stage subscription based enshittification. Which means its typically a labor of love or a government org has a long term understanding of Software as a Infrastructure (as opposed to SaaS)
I would sooner trust a GPL-licensed remote software program than store a kilobyte of personally identifying information in a proprietary "local first" system.
