I usually never spotted any kind of critics on the zcash forum. Look over at twitter/reddit/trollbox/tradingview chat etc. nobody likes the idea that 6 guys did the trusted setup together days ago already.
In this setup one has to trust, that they won`t print money. No thanks.
They should have had Craig Wright and Gavin Andresen participate so we know it is really trustworthy!
Lol are you serious?
If not that was a good joke.

Of course that was a joke! Didn't think I needed a /s on the Monero Speculation board!
Although the underlying point was that Craig managed to convince a reputed bitcoin guy that he was Satoshi using cryptographic sleight of hand. So not impossible to think someone couldn't do the same to 6 other crypto dudes (or even just 4, given 2 of the 6 were Zcash principals (Zooko, and Andrew Miller, an "Advisor" to Zcash). (And, ironically, another advisor to Zcash IS none other than Gavin.)
Looking forward to seeing Peter Todd's write up of the process over the coming days. But I've already seen one reference to "boxes of new computers", which was the same claim made by Craig Wright.
