Let me explain.
I am a missionary working in Sub-Saharan Africa trying to fill a hole in the medical care here. In a developing country there are expected and predictable shortcomings in the medical system and I find myself trying to help cancer patients where the State cannot. Now, the tempting mindset is to hope that the State never actually develops enough to do what I do, thus, I never find myself redundant and always feel needed and like I’m filling a purpose. That is, of course, a horrible thing to hope. Of course I hope my service is redundant soon and of course I hope that what I do won’t be needed soon. That would mean fewer people were suffering! That would be great! It would also mean I’m no longer needed and I could find myself and my family in some trouble looking for a new place to serve.
The “I hope the problem never goes away so I never find my cause pointless” mindset is what is likely going on here. Erin McElroy of the SF Anti-Eviction Mapping Project likely dedicates her (his?) entire life or, at minimum, most of his (her?) emotional energy on this project and so any progress Google and others make to help things get better means Erin is more and more redundant and less and less needed. That is a scary thing for someone who lives for a cause and therefore, while fighting for their cause, there is often a self-defeating hope that the cause never actually succeeds.
That’s just what I’ve noticed in the “I have a cause” field at least. YMMV.
