IMO Kori didn't come across well at all when she was on TSL early last season. Back then she obviously was on good terms with Dave. Clearly they have had some kind of falling out since, which is not at all surprising giving how Dave operates.
Now. Jonathan might have been a bit melodramatic with his initial tweet. But he is a really nice guy in addition to being pretty clever and witty. I really haven't seen him be mean spirited or bitchy just for the sake of it. That is more Dave's MO..
So while Jonathan may have exaggerated a bit, I absolutely believe that K & R sent him some unfriendly correspondence, so to speak. They probably targeted Jonathan precisely because he's not the type to be vindictive about it. If they have an issue with TSL and Dave, they really should have just messaged Dave IMO. Dave makes 99% of the controversial comments, so that is where the blame needs to be placed IMO.
I also think it's sad that some people here are mocking Jonathan and making fun of him. I also don't know why people who don't care for TSL just don't watch it or comment about it, but I guess people like to complain.
