Protected or not, companies, as well as governments, are known to be negligent. Too many times, radio astronomers find contamination in their bands that affects the sensitive observations. Frankly, it is not yet clear to what extent the new constellations will affect radio observations. That will be known once the satellites become operational. But if we are not vigilant, it may quickly happen that an “unfortunate mistake” deprives astronomy of precious parts of the radio spectrum.
