I'm working on a similar thing, except making sure we can actually live up to that promise: that means making the software entirely feasible to run on-prem (i.e. on your own computer), on your own cloud infrastructure, or provided by a third-party provider of your choice. (We chose AGPL3 to avoid the obvious problems with third party hosting trying to add features or change things and then locking you into their platform.)
Of course, this takes a bit more effort, and some things like Plaid are nearly impossible to use when self-hosted, but we've found some pretty good workarounds for that.
