The e3 is just a trojan horse hiding the true f3 eth asic on bitmain warehouses. The e3 was created to simply hide the fact the f3 exists, so eth devs would just see the e3 as "is not a threat to the network" and to send a message to eth devs that changing the algorithm will not brick the e3, meaning that was especially designed to be an amazing trojan horse. As I said before, I knew bitmain would launch something else to hide the fact the f3 exists, so eth devs would just accept the fact that "its okay to leave the e3 be" and eth devs are falling for it hehe
