Oh yeah, I think there will be a ton of the free YT viewers from last year who will revert back to Jomez instead of deciding to finally bite the bullet and pay for DGN. I'm definitely one of them.
The free live coverage was a convenience thing. If I was home I'd put it on as background noise, if not I'd just catch the Jomez coverage the next day.
I don't have any experience with DGN, but it seems like the biggest gripe is once the live feed starts you've gotta watch it live. Can't pause or come into the feed late like on YT and fast forward through all the commercials to get caught up. They take a while to make the live feed available to go back into afterwards and watch with those capabilities so unless you're watching it live you might as well watch Jomez and not pay.
