The Ordinal hype is still there but somehow the mempool fee is considerably down now. You may get the low to medium priority in 27-28sat/byte and this number looked like a dream few weeks/days before. Although it is not so low but still now we can make the transactions if we were waiting for the low mempool fees and those pending transactions now can be executed.
This spam attack has always had its ups and downs. It may be because of the scam market, since that is how they have been able to sustain the attack.
Like any other market (eg. the altcoin pump and dumping market) it has ups and downs meaning times where more newbies are falling for the scam and try to buy that garbage in hopes of making a profit hence increasing the "volume" and the number of on-chain spam.
But after being scammed, losing money, etc. they go away and the "volume" comes down which means less Ordinals Attack on Bitcoin therefore the small drop in fee rate.
However, just like the pump and dump altcoin market, this scam market is not going to die as long as there are newbies and gamblers who would buy the junk hoping to make a profit.
This is why as long as the exploit in the Bitcoin protocol is not fixed, this attack will continue and fees will spike.
