I'm not sure why devs are always acting in favor of miner but not bothering about end-users. For the case of bitcoin also they are not going for long-term solutions but they adopted just the time being solution of segwit. That is the reason we are currently having very huge transaction fees again along with ethereum.

I believe etehreum devs are simply following same kind of tactics which is the reason they are not hurrying to find a solution for their scaling problems. At the same time, unlike bitcoiners, dapps people might start looking for alternate platforms for hosting their project. I believe it is already happening and it may go more intensified in near future if ethereum devs will not solve the high transaction fees problems at any time soon.
