From Kendra Scalia's Electronic Visit Verification (EVV) is Here: What you need to know and how to get involved:

"Whatever may come to pass, the disability community is clear: We refuse to be treated as patients in our own homes.  My house is not an outpatient hospital or nursing home.  There is never a reason for the government or their vendor to have access to the private dealings of my life solely to prove I am disabled and in need of assistance."
