I'm looking for any reason why the transaction fees drop but I can't find anything.
The only thing that I notice is the massive drop in transactions these days according to Blockchain transaction counts chart.
It seems that people are no longer panicked from recent FUD events or is there another reason?

If this topic is pointed to the miners about fees miners don't have full control about the fees. The transaction fees suggested by mempool.space are based on network congestion and it is just an estimation not so accurate, by default mining pools prioritize transactions with high fees to give incentives to their miners.
Only mining pools have full control of what transactions they would like to add on the block they mine not their miners(except for individual or solo miner with big mining farms.)
