Monero guys believe in trusting no one, so with XMR I can only send a tx that 1) no one can stop from being mined 2) no one else knows the details. On LN nothing stops colluding routing nodes from creating a graph/profile of LN users and their activities and knowing the full amount transmitted, and nothing stops routing LN nodes from simply censoring certain senders/receivers on their route. Not good, we like privacy and censorship resistance above all, even if txs are "published", or permanent
