Why is this being done? Because cellular systems are protected assets of the Operators that own them. Many boosters in the market cause problems for those networks (which means all of us using the networks too). New FCC/Operator approved boosters are better and don’t cause problems, and Cel-Fi is the only booster in a special class of boosters that allows 100 dB of signal gain (30 dB or 1000x the gain of all other boosters).
