Actually, I'm way too far from this pessimistic paranoia that took over AVSIM entirely. If MS will allow 3rd party developers to provide their content to end-users independently (like they do now) and WITHOUT mandatory submission via Windowns Live or whatever it would be, I see nothing death-threteaning to the hobby.
As far as selling MSF in blocks (i.e. Hawaii, Europe and NA in separate pieces), this has been just a case waiting to happen and it happened, so I see no surprises here as well.
