As far as I know, bitcoin is being hated in the darknet since it was proven that bitcoin does not offer complete anonymity. It maybe the factor why bitcoin boom in its early years but that was long passed. Bitcoin is going to mainstream now, it is not the illegal merchants but rather legit company that wanted to take advantage of the boom making it to boom more.
Not hated perhaps, but they're definitely looking for better options to suit their particular need for secrecy/privacy/anonymity. Monero at least since 2016, and surprise, surprise Ethereum have now displaced Bitcoin as the dark markets' favourite cryptocurrency.

Last year, "illegal transactions" as percentage of total Bitcoin volume dropped from 50% to 20%. $225 million in cybercrime so far, with Ethereum.
