I have seen this too, and queried it through support for the AMKT project.
The reason is simple enough (lack of permission), but the rationale behind it is not so evident. It's simply that Atlassian do not permit you (or I) to create issues in those projects. Sure, it might have made more sense to restrict the CREATE_ISSUE feature to remove the tempting 'create' button, saving you a ton of time entering the issue in the first place, but I'm sure there are reasons!
The path you should take involves logging a support ticket, rather than create an issue. If valid, you may be rewarded with a public bug ticket.
