isnt there too much privacy project out there ? I dont think not many fancy private transaction, if so the other privacy coins would be doing well wunt they ? example ETC vs ETH
Yes, there are many privacy coins and only a few will be used. Monero is the most well known.
Monero is a fork of bytcoin but, now it's way ahead of bcn in terms of usage and use cases. It's best privacy coin out there
Actually, Monero is not private it was used to be.
Something like dusk network has a great chance about that. Because no chain is offering high level of privacy.
Why not, what is changed now?
Monero is a pretty solid project and is widely used in black markets. I don't think that anyone would be able to replace it so easily.
I don't know what changed but you can see an article about it: (Headline is: Monero Privacy Protections Aren't as Strong as They Seem)

Competition will always increase the ease of use for the common man. I think monero still have plenty of issues which can be resolved from other projects.
Monero may be the top privacy coin at the moment but it can be replaced if people find bugs or develop a better coin.
