As someone who manages the vault warden instance for a nonprofit with many volunteers but no fulltime employees I see this as a wonderful thing. Yes bitwarden has a nonprofit discount but no playing wack a mole with which of the 20+ volunteers are active at any moment to avoid getting a huge bill isn't worth it vs self hosting.
I'm in a similar situation, having many volunteers does not mean we have the budget to pay 5-10 euros per month for all of them for all the tools needed for work. Self-hosting and managed hosting of open-source software are the best option for us, including SSO and password management
