"Our Marketing team is excited to share moments that spotlight the magic of your events. In order to accommodate the specific needs of every user, you have the option to opt out of Section 7 by sending written notice of your decision to opt-out to legal@eventbrite.com."

So Eventbrite asks for a 'written notification' after you've setup instead of using an opt-in setting during setup, dirty fuckers.
You could see them eventually either monetizing this content through advertising... or a SaaS subscription for all the people who couldn't attend a particular event.
Can also imagine that this might make the speakers/presenters less free-er to express themselves, knowing their content will be re-corded in perpetuity and can be used or mis-interperpeted against them at any point in the future.
It's not that it can be used against them. It can be sold by Eventbrite as a conference recording with no compensation back to the conference or speakers.
Basically this is a clause that "Nobody who makes a living selling their words, music, etc. should ever agree to participate in any event organized using Eventbrite."
