He probably fears Quark since it's a contender and is growing rapidly.
That's why he is desperately trying to bash it.
No, I actually have nothing against Quark. I investigated it in an unbiased manner to see if I should buy some just to cover all my bases. My personal analysis of the coin's fundamentals was grim, and just about anyone I saw talking about the coin in the Quark community, even pro-Quark people, all agreed that the coin is currently not in a very good state.

The Quark moderator flat out loses in technical point discussion to that guy, no name calling or anything. And after his presentation, all they come up with is "Please don't attack our moderators and spread FUD in our community." You got to be kidding me. They're basically admitting the coin distribution model is broken, but it's rude to talk about it!
Quarks distribution model is genius
It might be genius if it was a proof of stake coin, but it's not.
