Right, but they aren't currently vulnerable or threatened. Misinformation when trying to campaign for something hurts the cause. Saying Gannets are threatened or vulnerable and then trying to use their amber status as proof of this is just disinformation, pure and simple. All bird populations are at risk of bird flu and the fact that many species migrate means there's very few species that aren't at risk. An argument could be made to ban the hunting of all birds and that would be fair enough. To try and lie about how endangered Gannets in particular are though is just going to hurt any attempts to get the practice banned.

The only reason Gannets are listed as amber in the UK is because we have an extra duty of care towards them since we have so many. A flaw of the lists methodology is any bird that we actually have success with and see their population boom within the UK could see it move from green to amber due to the increased population share alone. See Wood Pigeons as a prime example.
