You talking about something that's already been fixed mate, Ethereum transaction fee is no longer a problem and August is close which we will see even better and cheaper transaction fee on Ethereum network, the headache is already over, as for the question you asked many people just prefer ETH and you and I can't change their minds
Most people don't consider the price fixed, maybe after the August hardfork we might see a remarkable price drop in transaction. People don't use ethereum because of the transaction prices although when compared to Binance blockchain, it is significantly low. They also consider the better smart contract, the DAPP compatibility and Defi use.
