Not disagreeing, but they probably use a large portion of that money to actually pay for the organization, venue, designs of the compendium, the staffs, and everything else involved with the International. All that can't be cheap so I'm not sure which portion of that 75% is valve's profit. Does anybody have any ideas?

I don't think it's really meaningful to look at it like that. The tournament isn't funded specifically by sales of the items which contribute to the prize pool; it's just a general marketing expense to increase the number of players. Even if everyone decided to boycott compendiums for some reason, the whole thing could be a net profit if they spent the same amount of money in the dota store on other things (actually, it'd be more profitable...).
