Why was the change implemented?
Initially, the Auto-Address change was turned on by default. Then, it was disabled and a toggle was implemented to manually enable this feature. But due to the maintenance cost and the lack of demand, it would be a better experience for all to just completely turn it off.
Lack of demand? How did CZ, Binance, Trustwallet developers know that people do not want change address? They are looking for ways to make bitcoin centralized, they created their own centralized coin, they pegged bitcoin and deceiving people to think they are bitcoin when they are altcoins, and see an obvious lie again and ignorant people like Guessti believe this.
