I think they will lose more money especially because its a major. I'm not 100% sure of how it works but there's most likely some sort of auction for each organiser to get the major. Tournaments are generally not held for profit but rather to build the brand. I went to two majors and both were quite cheap, I looked at normal tier 1 tournament prices and they were along the same price.
Renting a huge venue, setting up the stage, working on the production, hiring talent, getting the pcs, chairs, practice rooms, all the electronics, renting hotel rooms, paying for advertisements etc... There's a shitton of expenses that don't get covered by ticket sales alone, they could probably sell the tickets for higher prices because its a higher class area but for that fact aswell the venue will be more expensive to rent.
