I bolded the part where your logic breaks apart. You demanded 'guarantees' in your earlier post. And they 'better deliver' on it, presumable 'or else...'. But to be able to guarantee anything you need to be certain. Now you concede that they can, at best, be 'reasonably confident'. But that is very much not the same. Lets give a simple example. Let us suppose they give us a roadmap until end of 2020, with twenty things on it. They are 'reasonably confident' (lets say 90% sure) about each item on the roadmap. That means the odds of them delivering the entire package is .9^20=.12, or 12%. In other words, the odds of you being upset and frustrated even when they are 90% sure about each individual item will be 88%. So if they are reasonably confident about those things, they would at the same time be reasonably confident they won't be able to deliver all of it! But with each individual item being at 90%, they would also be reasonably confident that they would be unable to point out which one will be undelivered.
To actually be 'reasonably confident' about the entire package they would need to be x^20=.9 confident about each individual part. That resolves to a required certainty of 99,5% about every single thing on the roadmap. Unfortately that level of confidence simply doesn't exist in reality. So either you demand guarantees, or you expect 'reasonable confidence'. But you cant have both, how tempting it may intuitively sound
Well,we have neither now. We have radio silence and only the occasional "hey don't worry it will come eventually" intervention when people moan too loud.
Sorry but i don't call this responsible management of the community.
