Well the only tiny grain of truth in that statement is that a static
port can be occluded by a
foreign object. On the ground this can be something like an insect
setting up housekeeping
in it, in flight ice is probably the biggest risk factor. Since loss of
the static port will bugger up
3 basic flight instruments (altimeter, ASI and VSI) this is non-trivial.

Or masking tape left in place after maintenance. At least one airliner has
crashed because of this. Many fatalities.
