Does any software have a survey for what users want? Instead of immediately pushing AI, they should have pushed a survey where AI was one of the choices/questions.
It is either a fork or new software based on what a people really want or need. This is not an easy hill to climb.
Unfortunately, "configuration" is the survey. I detest both configuration and surveys. Modify the open source code and rip out the Artificial Inference code because Firefox is open source, or build software from scratch: servo, ladybird, your own web browser based on a survey.
