Exactly. This seems a tentative to control and sanitize that goes beyond the scope of a community and organic event. This is not an English event. Yes, talks are in English, but some people just have difficulties asking a question in English, they take longer, and sometimes it’s hard to understand them, It doesn’t mean they shouldn’t have the same opportunity to speak.

The one thing I miss is an active MC that can take control of the Q&A as an effective mediator and authority.

Vetoing questions or requiring them to be submitted in advance is against the concept of these events, in my opinion.

The MC should have (I believe already has) the authority to stop a question if it goes beyond scope, it’s either incomprehensible or not even a question. As the speaker has the right to not answer it.
