Actually, if we have blocks just slightly over 50%, it increases gas fee very fast. Only after many blocks that are almost empty or below 50% does the gas fee start to fall to reasonable level.
I suspect it's all just for purpose of manipulating the price, it's not about users. Greed has taken over, now all they care about is writing news about how much ETH they burned this day or this week!
Also notice that miners still get their fair share, but the system is robbing the users, only because they want to rave about burning ETH. Miners are still winning, price manipulators winning, users losing.
