It's not just recently. I stopped using Ethereum a long time ago but I still remember the congestion caused by a game called crypto kitties. As we all know when a network is clogged, users tend to increase their gas fee in order to send their transactions faster than the rest.

I don't know what the miners expect to make ETH to the point of consuming very high gas costs and frustrating everyone, not even just investors, bounty projects also suffer from this gas problem.
Let's not put the blame entirely on the miners especially when the design/code itself couldn't handle the number of transactions on the Ethereum blockchain. Don't forget that it's still on POW and layer 1 just like Bitcoin.
