That wouldn't surprise me. I never assume it's because of the reasons in their critique of crypto, so I hardly ever speculate on their motives.It's not for any of the reasons you have given so far for people to be anti-crypto.
You'll be disapointed to learn that it's virtyally impossible for everything on Ethereum to be fucked up to the point the whole thing collapses.
There's just too many other tokenised assets other than Ether on that blockchain and now, they are offering a $1 million USD bounty on any critical bugs.
Some users are bound to have problems, but there's a reason why there's a whole bunch of different software interacting with that blockchain. It's called client diversity.
