So I saw on this post the upsetting information that fedora is blocked on cuba, and I Wanted to check if the same was true of the downstream distributions, in particular open SUSE tumbleweed, as well.

Edit: By what it seems they put it there more as a way to reduce liability(once the us trade embargoes seem to include most anything with US developed technology, although I do not understand that very well or if it does apply to open source stuff), in case the US comes a looking, because it does not describe any tools or measures to prevent it, in fact it even states that it is not geoblocked anywhere.
