His argument is that you can only track right now due to extremely low usage of MWEB. Even that is not 100% accurate, as there would still be no definitive proof of “who” sent it, only an assumption (though fairly accurate assumption as of right now).
I’m just happy Litecoin gives this option, just fear 99% of people do not care enough about their own privacy for it to be meaningful.
I believe most who view privacy as the #1 requirement will still flock to Monero, but people will still use Litecoin as the most trusted, legal, fast way to send payments on a decentralized blockchain. These 2 blockchains are NOT competitors and will coexist as complimentary options for a very long time.
