The issue here is that essentially nobody who has used/uses Tornado Cash is technologically inept enough to not know how to use something spun up as an onion service or eepsite (would help lessen the severity of the reduced anonymity issue), if the tornado cash folks don't just use IPFS to host. Regardless, the website is merely a GUI to make things easier and not necessary for functionality in this case... or is it somehow necessary?
