I feel like you are focusing too much on procedural matters like the number of directors and the identification process for online meetings etc. They are permitted to have online and hybrid AGMs now, and despite what you are saying I have never been at a meeting where each attendee, online or in-person, is identified. They might say something like: "we have 60 in attendance this evening, 40 here in person and 20 online". You keep talking about the online vote supporting the board's positions - what positions exactly? What kind of votes are they having? Any CU AGM I have been at have had very boring, technical votes, elections and votes for the dividend, but little outside of this. Are the online vote results diverging from the in-person ones? Again, how do you know this?
Everything you are saying seems very vague. Having said that, the fact that they have had 2 special general meetings to elect two new board oversight committees would tend to support your suspicion that there are serious governance issues. The cost involved in an SGM is fairly big so to have one of them for that reason is strange enough but to have 2 is bizarre.
