Einstein showed that the effects of gravity were indistinguishable
from acceleration.
People are confusing weightlessness, where the forces of gravity are
balanced, with the absence of a gravitational field.
Moving the GPS master clocks to the satellites would indeed bring in
relativistic effects because they are accelerating continuously.
