Yes but if ente goes bankrupt even if the code is open and free (AGPLv3 if I remember correctly) it doesn't mean that it will find maintainers and even if it does the nooby customers will have a hard time knowing and transfering to the new repo/fork. For these online services I totally understand that people prefer stability and sustainabilty over privacy. Remember CTemplar, Skiff, etc..? Companies like Proton, Standard Notes, have proven that you can run a privacy business for over a decade but that does not mean every privacy product or services will sustain that long.
