The money made from the online portion is used to pay for the offline portion and not for tournaments like IEM or ESL One, that was my point. Whether or not they use the viewing numbers etc for other purposes was not the point and not something I have any insight into.
I never said online qualifiers don't exist. There are obviously plenty of them but they're mostly for lower-tier teams like AGO, LDLC etc. Top teams like Astralis, Liquid, MIBR etc never have to play online qualifiers since they're always directly invited or they just wouldn't attend.
