Also, the original purpose of the channel was for active security issues and those are discussed regularly. It isn't practical to expand access beyond the primary witnesses, core developers and major stakeholders without making it unusable for that purpose (in which case another private means of communication would be needed before long and quickly be created).
There might be some impression that people are on that channel having secret discussions all the time. That is not the case. It is used sparingly when issues arise that need attention from these parties and the rest of the time, not at all.

Thank you for the clarification!
I even think there is no need to explain what you do there. It's your right to have an own chat. Nothing wrong.
