Miners certainly benefit from what I personally call "ordinal madness", and suffice it to say that in recent days the rewards per block amounted to over 10 BTC, and considering that the reward without fees is 6.25 BTC, it is clear how much their profit has increased. Without going into any conspiracy theories, isn't it logical to think that some of them (miners) have their fingers in all of this? Who knows, maybe we'll find out one day.
I also believe this that it's the miners who were the first beneficiary of this experience we are all having with high transaction fee, but we can also take a look of it from this angle, this wasn't what they already planned for or knew coming base on my personal understanding, the block size was increase to allow for more capacity that can contain more Bitcoin transaction thereby leaving the mempool less congested before the realization of the other use case of this same space.
But on ordinals inscriptions and miners took advantage of the whole thing to make their own income from it, which if we were also in such possible could possibly do the same by accepting what pays higher as our first priority before considering others.
