Yes, Fedora is related to Red Hat. Red Hat does not own Fedora, but is heavily involved. Fedora remains community driven however. Have a look here for some more detail on this.
And on the matter of Fedora being blocked in Crimea, this is not a decision made by the Fedora community or by the Crimean government, but rather by the US government. It is my understanding that this is a sanction as a result of Russia’s annexation of the region.
You can see information from OFAC here about the US export control ruling.
Fedora is complying with this due to the Fedora Export Policy
Ultimately, there is no legal route to use Fedora in an export controlled region, which sucks.
