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.
Miners are the highest beneficiary of these ordinal inscriptions and many of them will always support the project because the profit is huge. It will take selflessness and love for Bitcoin for these miners to block these inscriptions.
miners do not choose the transactions, they dont disregard transactions either.. becasue they have nothing to do with creating a block template... they just get given a extra bonus for hashing on a pool. where the pool manager makes the transaction selections for blocktemplates
its like Apple employees dont set the price of the new iphone nor the malware thats on the OS. they just benefit from a christmas bonus if their sales period reached more then its target
the pool manager could change his blocktemplate scripts to ignore transactions it doesnt validate content of(the junk) but pool managers dont get to keep the majority of block reward so their greed to maximise their X% commission makes them want to accept junk for the expectation to keep fee wars going
