Someone rightly said: "Because the coolest players are those who play with the SoD ruleset. And SoD is garbage."
True SoD players will say that to a WT player.

So far, I'm seeing the opposite. SoD players criticize WT for the inappropriate behavior in the WT chat, and SoD players themselves say that SoD is garbage, reveling in the offense caused by the words they themselves uttered.
And at the same time, true WT players are organizing a tournament that will include both SoD and WT – this is an ultimatum.)
And yes, it will be lively.

P.S. Regarding Michurinsk, as far as I remember, the main reason for refusing to play was the mandatory entry fees, because it would have been possible to create a version of the game by agreement for SoD.
