Thanks for your feedback.
Yes, we removed the dashboard widget from the Meta Box AIO and MB Core plugins and added 3 news items to the WordPress News widget (we didn't remove the existing links, this is probably a bug and we've fixed it in recent commits). We think it makes the dashboard look seamless than before (the previous widget is too big and confuses some clients).
Anyway, we've just added a commit that allows users to dismiss the Meta Box news if they don't like it, which is pretty much similar to the previous options in the Meta Box AIO. This change will be included in the new plugin version.
