They might be able to make requestable the connection requests to outside sources (which I expect is something many extensions use, even those without data collection), but whether those requests relate to data collection is not something that can be determined programmatically.
Yes, all access to outside sources is blocked by default and users are asked on a per URL basis with the author manually requesting each URL access including a reason – with occasional manual validation from Mozilla staff.
