I mentioned a little in my post above. I would guess the beginning of the end of their friendship started with HHN. Peter/Kitra were invited to the media preview, which meant they could video the inside of the houses. TTT was NOT invited out. But TTT put out a video outlining each of the 10 houses with footage from each of the vloggers that WERE invited and able to film. So it's was Paging Mr Morrow, JoJo, Ordinary Adventures, Dev, that Panda guy I think, I don't know, there were a bunch. TTT technically gave credit for the stolen footage, but they did not ask permission. This was confirmed by most of the creators when people, mostly from here, pointed out that TTT used their footage. Oh and the credit was in microscopic print on the bottom corner in a text color that you could barely see.
But Peter and Kitra have become more and more successful and their videos are actually quite informative. They know their tit, especially Star Wars stuff. But, just compare their Minion Cafe video to Tim's, there basically is no comparison, it's leaps and bounds better. I think the more invites OA gets, the more jealous Tim and Jenn get and OA is just another lost friendship to add to the very long list.
I am also a Bright Sun Films fan. I really enjoyed their Penn Hills video, as we vacationed at a house not too far from there for many years when I was growing up. Also, the Costa Concordia video is also well done. All of their videos are very interesting.
