a. nothing changed on bitcoin, and if it still doesn't have privacy by default is it a "what" coin?
b. fake marketing is not the same as a "no difference", if bitcoin was a privacy coin the name privacy coin wouldn't exist and all of them would be, selling a privacy coin as a privacy coin would be like selling water but with the taste of water, but then you can fake market other things like scale, speed, etc
Is litecoin a privacy coin?
I wouldn't say so, litecoin markets itself as "the silver to bitcoin's gold" for being lighter cheaper faster etc, it did add a "privacy layer" called mweb but it works better for scaling than privacy, there is still a tx graph that can be observed and archived, etc, but that aside it's still in all major exchanges and hasn't been targeted for its "privacy capabilites" cause it's not that good, kinda like bitcoin's LN, it is a "privacy layer" but also doesn't make it a privacy coin
