Nothing unusual there.
Not unusual for shitcoin shenanigans

It's just a company with workers and all other crap.
If I start to name all the shady stuff in zcash I would probably need days to finish with eeverything.
Now even if zcash is to become without this trusted setup they will always have this suspicious shady history and it's never going to be widely accepted.
If you want to talk about shady history, look at Monero's Cryptonote origins with the Bytecoin scam [2] and the purposely obfuscated inefficient miner software [3]...
If you look my previous posts you will see that I said the same thing for monero, but they are still better than zcash sin almost anything.
Some people even say that one country secret service (I won't name the country) is actually the one who is behind everything done in zcash.
Now if you look at nationality of some scientists who worked on zcash and place they worked, you will understand better, it's not some anonymous guys like in case with Bitcoin.
