While the 18C being at 14.0 is completely fair for this plane. It very clearly lacks in countermeasures, in real life they we’re given the AN/ALE-56V Mongoose chaff and flare dispensers. Source 2nd Source
Bug Report it.
Chances are, it’s already being worked on. The Dev server isn’t the finished product.
Reading through your sources, it seems that they are talking about the F/A-18E, which is not the variant being added to the game right now.
On the first source the Super hornet is specified by putting E/F behind it, which was only noted for one version. The rest can be mounted on the Legacy
And on the second source the 9th page specifies testing with he legacy hornet

oh neat
Your source notes that the A/B variants tested it as well, meaning that all variants of the Hornet should get the pods. The source on the bug report noted that all of them can be equipped with 4x of the Saab 160 CM pods. Between that and them supposed to be having 120 flares, the Hornet should have even more countermeasures than the Gripen.
Because it’s labeled is accepted does it mean it will be fixed?
Nope, it’s labeled as a suggestion, which means it may or may not be implemented.
Says it’s accepted
As a suggestion.
Spoiler
If there are enough sources that indicate a vehicle could equip a piece of equipment, and it is not already on the vehicle ingame, Gaijin will accept the report as a suggestion. Then the devs will decide if they want to implement said equipment.
