From what I've read, Zcash (formerly ZeroCoin) generates a masterkey that the devs have access to, that allows access to the complete blockchain, so you are trusting that the devs don't take advantage of this and delete the masterkey.

How retarded is that? Who would trust such technology?

You are somewhat over simplifying.  The devs are supposed not to have a master key ; the whole problem is how to generate the public parameters without someone holding the masterkey.  It is problematic, but it is not as blunt as you put it ; I agree however that what I understood of the way they generate it, that it is sufficient that the whole set of celebrities supposed to generate the key, collude over keeping the key (or that there's a back door in the system they use that can bring together all the shards of the golden key), to have the golden key that can generate an unlimited number of coins.  It cannot de anonymise however.

I think more work is needed on this "trusted setup" before it can be trusted, but it is not as blunt as you put it.

They have not released anything official yet so let us see what is in store for the future. I believe they have mentioned that they could still change the algorithm and the implementation for zcash. So having the trusted set up could not be a final proposal from them.

Yeah, inherently zero-knowledge is superior to anything else but if you investigate Zcash its like a bitcoin sidechain with zerocoin, they even copied the bitcoin core, nothing evil about that but this means you have 2 systems: one with the trusted-setup to generate anonymous transaction (which take several minutes and need 8 GB RAM or more btw) and the transparent bitcoin system, also 20% of mining goes to the founders. I will wait for the future if some smart guy figures out how to make this without trusted setup and without the transparent bitcoin core.
