The FAA does not "ignore" Angel Flight.

You posted some stuff regarding tax deduction and the FAAs decision
that that is not "compensation". However, the FAA chooses to ignore the
fact that Angel Flight would normally be considered part 135 because
there is no common purpose of flight. When I was serving as the area
Angel Flight check pilot instructor it was made clear to us that we
were on non-solid ground and unsafe flight could easily get the entire
organization shut down.
