I'm on board with your dissatisfaction for sure. I mostly mean to suggest that what there was to say has already been said and whatever will happen will happen regardless of continuing the discussion.
Lack of communication does hurt, but I mean look at which developer we're discussing and what game we're anticipating. I think it's unsurprising how little has been communicated. Again, this isn't good, but it is to be expected at this point.
Beyond that, I do disagree with your doomsday predictions, I think you're overestimating the problem. There is a massive difference between servers during the beta and servers during early access. Like I said, beta invitations are literally that; invitations. It seems exclusionary for sure but nobody is inherently entitled to receive an invitation.
But early access is completely different. Instead of Taleworlds excluding certain populations out of convenience as with the beta, to not have prepared servers for all regions when all regions will suddenly overnight come to include paying customers is a bit of an extreme possibility.
The beta isn't a service being provided to the audience(mostly, at least), it is supposed to be the opposite; a chance for the players to provide their testing services to the developer.
When the game finally does begin to sell, that relationship becomes appropriately flipped. Customers are paying for services, and for those services to be missing would be particularly egregious. I mentioned refunds being a possibility, which is the arena that things will shift to. Excluding people from South America and Oceania during the beta doesn't "hurt" Taleworlds, really. But excluding those same people(and the many, many more who didn't sign up for beta testing) from a service that might be the pivotal factor deciding purchases is a clear financial blunder.
I've been ranting for a bit but all I really mean to say is that I think you can have slightly higher expectations for early access if for no other reason than that it is in Taleworld's financial interests to meet expectations, unlike during the beta.
