These were able to pay high fees because their pump-and-dump markets had high profits. The suckers have mostly left those markets. But Runes moved from Ordinals to OP_RETURN TXOs a few months ago. They're occupying about 60% of each block, as thousands of small transactions, not large inscriptions. They're the reason that rates are 2-4S/vb instead of 1S/vb. Counting Ordinals isn't useful for monitoring these transactions. The fee surge mentioned in the top post lasted about 10 blocks, not a doom and gloom event
A quick look at one of the blocks shows a lot of RBF fee-boosting. We can hope that the Rune OP_RETURN transactions were automatically paying RBF fees of 400-700S/vb in these blocks, wiping out their meager pump-and-dump profits
