Why Porn industry hasn't adopted Bitcoin technology (Lightning Network ) as their go to payment system?!

Apart from all the bad side that porn industry might have; I have always admired Porn industry to be the first ones to adopt or push technological advancements but I haven't seen this push for BTC overall.

I am aware Pornhub does have something related to it but it doesn't seem to be at full scale.

PS: I am not talking about the shitcoin industry of NFTs etc etc. I don't care about them.
