Hi Simon,
no strong opinion either way. I think it has some merit to not have archives for some discussions, and then it indeed is a challenge for future boards. On the other hand, in particular now, I feel it will be a challenge for future boards anyways, but that’s a different story…
Indeed, if anyone assumed on the directors list would be a vivid discussion, it’s usually not. I think we should all remind ourselves to have votes and discussions in public whenever possible. There will always be some discussions that cannot be (immediately) made public, but not all of the votes taken needed a private vote in first place, I agree.
Oh, I would agree on that. 
I don’t want to dig into the past too much, but I think a big reason for this in the past was a certain amount of, let’s call it, suspicion and desire to steer, control and micromanage. In such climate, things don’t work out properly. If people’s decisions are driven by fear, that is doomed to fail.
In addition, some wrong decisions ware taken (or rather, some right ones were not taken), ending up in a situation that we are slowly unwinding, but fixing things after the fact is much harder than doing things right from the beginning.
We are slowly getting to a better situation, hopefully.
On that I am much less worried. Meetings are meetings, separate votes and decisions are another thing. I’m fine if they are stored differently, that’s what I know also from other organizations.
Absolutely, TDF has seen way too much fights sadly, and still sees it up to today.
