Just want to clarify a few facts:
1) Ani Maamin is not about Q&A sessions but rather educating parents and educators to have clarity in the ikrei emunah so that they should be more passionate when discussing these inyanim (as we should be). This has nothing to do with Chakira, if you dont believe me, just join one of their parent or teacher training seminars as I did, or listen to some shuirim online.
2) The sign was against the first ad not the second one posted here. The first ad was too strong and it
unintentionally implied that the seder is a time for addressing questions, therefore the organization changed their ad to avoid being misleading and the rabbonim issued a statement clarifying that the approach of the first ad was incorrect. (If you actually read the sign it is not against the organization but rather the ad).
3) If you actually listen to the teleconference (its available on their website
http://animaamin.org/news/recording-of-pre-pesach-teleconference-now-available-free/) there is nothing about questions!
4) I happen to know that Rav Mattisyahu personally reviewed the notes for the teleconference before it took place and said that there was nothing problematic being presented, and that they were ready to cancel the teleconference if he would have disapproved of anything.
