Why did Character-marked skins suddenly stop being universal after Season 2?

Question — is everything so bad at DICE that after the second season they themselves forgot that skins marked as Character were universal and not locked to a specific class?
In the end, the skins I got from Season 1 and Season 2 Battle Passes can be applied to any class without restrictions, but skins with the exact same marking from Season 3 and 4 are locked to specific classes. Even though the game still has skins that clearly show which class they’re locked to
