Well, I agree somewhat. Read on

I'm actually quite surprised by the backlash against Jodi and Kevin. I hardly see them as evil, because the filmed interactions between them and the kids were adorable. I have not seen any evidence that they were compensated for all that childcare. Or paid for their time on screen, although it seems that they regret their participation now. Anyone can change their minds and regret actions.
Jodi took the kids for all those one-on-one days. Kate said so. Also Jodi and Kevin took all the kids (sick kids, IIRC) when Jon and Kate went for Jon's (elective) hair transplants.
Unless we were there for the conversations we cannot know whether or not Jodi and Kevin shared their concerns with Jon and Kate in a timely manner. By "timely" I mean before they were cut off from the children they had been babysitting. I do not really care whether that was due to a compensation issue or perhaps sharing concerns about excessive TLC filming that they gradually became uncomfortable with.
When was it that Kate stopped all contact? She just said 2 years ago. OK, April 2008, if we believe her latest statement.
We do not know, because we were not there, whether or not they shared concerns with Jon and Kate, with TLC/Discovery, or with state authorities before April 2008.
Yes, in May 2009, they did go to the press. ROL, CBS, whatever. Were they paid? I don't know. Do you? Have you seen the checks? If they were paid - perhaps they put the money into the TAP funds for the Gosselin children? Those State college funds Kate claimed were empty. I have no idea whether they did that or not. Neither do you. We can assume either way and some people topple over themselves to give Kate the benefit of the doubt.
Yes, assumptions can go both ways. From what I have seen Jodi and Kevin are doing the best they can in hard circumstances. In the video testimony I saw yesterday neither slammed Kate or Jon. It was also clear that they avoided doing so and also refused to respond to leading questions. Good for them.
Kate, on the other hand, slammed Kevin -- her brother! -- unmercifully yesterday as a broke money grubber. Her statement last night that he and Jodi ran to the press after every visit to the Gosselin home is patently untrue. They did not go to the press until Kate had cut off all contact. That is one thing they all agree about.
So, on balance, that makes me feel that Kevin and Jodi are more credible than Kate.
