I used it before all the 'questionable' info came about. Then I went in and flashed the updated SU app. From what I read the Kingo developers say the info they were gathering was for statistical reasons. I don't regret using it and I would probably do it again, I have the ability to flash ROMs now and that was the goal. I did go back and flash the updated SU app to ensure I was using the proper 'trusted' one.
