Sometimes we do not understand the important of network fees, Can we really share out thought and talk about the important of network fees to other wallet that is not Blockchain, this usually courses delays in confirmation and People do neglect it, And yet alot of people do complain on the delays ok there transactions.
I don't understand exactly what you are trying to say but if you think the fees go to the wallet developers then your information is not accurate.
You can send transactions with a fee close to zero (1 satoshi), but it will take a longer time to be included in one of the blocks and therefore you will have to wait longer.
But if you use a well-programmed wallet and track network activity
[1], you will be able to pay the lowest possible fee based on the estimates time to get confirmations.
